via the below links here are the important facts to why this trap works:
Once the mosquito bites a person infected or not, she then hunts for water in about 2 days to lay eggs. I have read she has been known to lay eggs in a water source as small as a bottle top. So she is very proficient. Also, water that has had eggs hatch is said to have an extra attractant of a pheromone. It is said for survival prefers to lay eggs at multiple locations each egg laying cycle. This is a major advantage for us by putting out multiple traps whether true or not but below shows documentation that it is true. The diseases are not transmitted for 7 or so days once a mosquito bites an infected person. This is about 2 egg laying cycle if we trap her she cannot pass any disease on. Next, plain water traps IE Ovi traps have been used to for even just mosquito sampling projections for over 50 years. And now a Canadian University found that an Ovi trap with just plain water inside tires can decrease the population. What this one-way does is dead ends 98% of the time any potentially infected mosquitos and the offspring are reduced so in time there are also fewer mosquitos addressing the problem two fold. Without poisons, replacing sticky materials, electricity and it accomplishes this very inexpensively. The least expensive in the world that should be just as efficient.

Aedes aegypti, the main mosquito species that transmits Zika virus and several other serious diseases, can breed practically anywhere. These mosquitoes will lay eggs in the stagnant water collected in bird baths or old tires, sure, but also in the few droplets gathered in a discarded candy wrapper, or on the damp surface of a fallen leaf, or in a practically-empty soda can.
....
Aedes aegypti are known as sip-feeders because they like to take little glugs of blood from different sources, a practice that increases the likelihood that any single mosquito will transmit disease to multiple people. If they can get into your house, all the better for them. Aedes aegypti like being indoors. They hang out in closets, under beds, and behind washing machines; often emerging around dawn and dusk for blood meals from people who usually won’t even notice they’ve been bitten until it’s too late.
http://www.dengue.gov.sg/subject.asp?id=12
Under optimal conditions, the egg of an Aedes mosquito can hatch into a larva in less than a day. The larva then takes about four days to develop in a pupa, from which an adult mosquito will emerge after two days. Three days after the mosquito has bitten a person and taken in blood, it will lay eggs, and the cycle begins again.Fast facts about the mosquito
Only the female aedes mosquito bites as it needs the protein in blood to develop its eggs. The mosquito becomes infective approximately 7 days after it has bitten a person carrying the virus. This is the extrinsic incubation period, during which time the virus replicates in the mosquito and reaches the salivary glands. Peak biting is at dawn and dusk. The average lifespan of an Aedes mosquito in Nature is 2 weeks The mosquito can lay eggs about 3 times in its lifetime, and about 100 eggs are produced each time. The eggs can lie dormant in dry conditions for up to about 9 months, after which they can hatch if exposed to favourable conditions, i.e. water and food
So after biting a infected person she can not infect others for 7 to 11 days is the timeframe. So if we catch her as she lays the first bunch of eggs from that feast or the second no disease is passed on. I have read they can live 1 month and lay as few as 20 eggs and prefer to lay the eggs is multiple locations which is good for our traps located in many locations give her her wish, she just needs to go in one of ours.
I have read the range is as far as 400 meters from the water source which is rare. The normal is 50-100 meters of the site of emergence, the closer options the better for our traps to be located. I assume they lay their eggs in the same place where they hatched when there are not many sites to lay eggs, but we offer more and closer options which logically should be preferable.
This mosquit has a adult life of 8 days to 2 weeks and up to one month some have reported..

Mosquito Host-Seeking: a partial review
Preface: I began writing this review but never completed it and have no plans to do so. However, some people may find this information interesting. There are sections missing, and much is incomplete. What is incomplete? Well, there's still a lot of literature out there that offers additional information which may clarify or contradict the information presented here. References mentioned here can be found in the accompanying bibliography. -John VanDykIntroductionWillis (1947) used a dual-port olfactometer to show that Aedes aegypti and Anopheles quadrimaculatus were attracted to animal odor (human arm). Haddow (1942, listed in Willis 1947 and Laarman biblio) showed that unwashed naked children were more attractive to An. gambiae, An. funestus and An. pharoensis than naked children who had washed. Dirty clothes in a hut attracted more mosquitoes than an empty hut. Individual variation in attractiveness to mosquitoes was shown conclusively by Khan (1965), who was able to isolate 1 person very attractive and 3 people very unattractive to Ae. aegypti by observing both bloodfeeding and probing reponses. Acree (1968) attributed differences in attractivity to the amount of lactic acid produced by the subject. Males were more attractive than females (Rahm 1958, in Khan 1965) and babies are not very attractive compared with men (Muirhead-Thompson 1951, Freyvogel 1961; both in Khan 1965).
Attractants
Many substances have been tested as possible mosquito attractants. Rudolfs (1922) tested numerous substances using an apparatus with two chambers and a connecting glass tube. The following table shows a partial list of his results (only positive responses are included in the following table:

Transmission of the Dengue VirusDengue is transmitted between people by the mosquitoes Aedes aegypti and Aedes albopictus, which are found throughout the world. Insects that transmit disease are vectors. Symptoms of infection usually begin 4 - 7 days after the mosquito bite and typically last 3 - 10 days. In order for transmission to occur the mosquito must feed on a person during a 5- day period when large amounts of virus are in the blood; this period usually begins a little before the person become symptomatic. Some people never have significant symptoms but can still infect mosquitoes. After entering the mosquito in the blood meal, the virus will require an additional 8-12 days incubation before it can then be transmitted to another human. The mosquito remains infected for the remainder of its life, which might be days or a few weeks.

egg of AE 550-700 microns long, 150-180 microns wide,
http://www.denguevirusnet.com/life-cycle-of-aedes-aegypti.htmlEggAfter taking a blood meal, female Aedes aegypti mosquitos produce on average 100 to 200 eggs per batch. The females can produce up to five batches of eggs during a lifetime. The number of eggs is dependent on the size of the bloodmeal. Eggs are laid on damp surfaces in areas likely to temporarily flood, such as tree holes and man-made containers like barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, discarded bottles, tins, tyres, water cooler, etc. and a lot more places where rain-water collects or is stored. The female Aedes aegypti lays her eggs separately unlike most species. Not all eggs are laid at once, but they can be spread out over hours or days, depending on the availability of suitable substrates. Eggs will most often be placed at varying distances above the water line. The female mosquito will not lay the entire clutch at a single site, but rather spread out the eggs over several sites.
The eggs of Aedes aegypti are smooth, long, ovoid shaped, and roughly one millimeter long. When first laid, eggs appear white but within minutes turn a shiny black. In warm climates eggs may develop in as little as two days, whereas in cooler temperate climates, development can take up to a week. Laid eggs can survive for very long periods in a dry state, often for more than a year. However, they hatch immediately once submerged in water. This makes the control of the dengue virus mosquito very difficult.
LarvaeAfter hatching of the eggs, the larvae (see figure 2) feed on organic particulate matter in the water, such as algae and other microscopic organisms. Most of the larval stage is spent at the water's surface, although they will swim to the bottom of the container if disturbed or when feeding. Larvae are often found around the home in puddles, tires, or within any object holding water. Larval development is temperature dependent. The larvae pass through four instars, spending a short amount of time in the first three, and up to three days in the fourth instar. Fourth instar larvae are approximately eight millimeters long. Males develop faster than females, so males generally pupate earlier. If temperatures are cool, Aedes aegypti can remain in the larval stage for months so long as the water supply is sufficient.
PupaeAfter the fourth instar, the larvae enters the pupal stage (figure 3). Mosquito pupae are mobile and respond to stimuli. Pupae do not feed and take approximately two days to develop. Adults emerge by ingesting air to expand the abdomen thus splitting open the pupal case and emerge head first.

During 22 May to 20 July 2000, immature mosquitoes were collected from 12,722 containers in 2,931 houses, of which 424 held ≥1 Ae. aegypti. A subsample of larvae and all 16,433 pupae detected was removed for study. Resting adult mosquitoes were also collected from the same houses as the immatures. Adult mosquito size was determined by measuring the wing lengths of 672 aspirated adults and 2,316 adult females that emerged from container-derived pupae. Immatures were most commonly found in rain-filled containers, located outside of houses, and without lids. The average wing length of females derived from pupae varied considerably (1.67–3.83 mm), with slightly less variation for females captured as adults (1.80–3.23 mm)

The use of vector surveillance tools for preventing dengue disease requires fine assessment of risk, in order to improve vector control activities. Nevertheless, the thresholds between vector detection and dengue fever occurrence are currently not well established. In Belo Horizonte (Minas Gerais, Brazil), dengue has been endemic for several years. From January 2007 to June 2008, the dengue vector Aedes (Stegomyia) aegypti was monitored by ovitrap, the sticky-trap MosquiTRAP™ and larval surveys in an study area in Belo Horizonte. Using a space-time scan for clusters detection implemented in SaTScan software, the vector presence recorded by the different monitoring methods was evaluated. Clusters of vectors and dengue fever were detected. It was verified that ovitrap and MosquiTRAP vector detection methods predicted dengue occurrence better than larval survey, both spatially and temporally. MosquiTRAP and ovitrap presented similar results of space-time intersections to dengue fever clusters. Nevertheless ovitrap clusters presented longer duration periods than MosquiTRAP ones, less acuratelly signalizing the dengue risk areas, since the detection of vector clusters during most of the study period was not necessarily correlated to dengue fever occurrence. It was verified that ovitrap clusters occurred more than 200 days (values ranged from 97.0±35.35 to 283.0±168.4 days) before dengue fever clusters, whereas MosquiTRAP clusters preceded dengue fever clusters by approximately 80 days (values ranged from 65.5±58.7 to 94.0±14. 3 days), the former showing to be more temporally precise. Thus, in the present cluster analysis study MosquiTRAP presented superior results for signaling dengue transmission risks both geographically and temporally. Since early detection is crucial for planning and deploying effective preventions, MosquiTRAP showed to be a reliable tool and this method provides groundwork for the development of even more precise tools.

Raw sewage as breeding site to Aedes (Stegomyia) aegypti (Diptera, culicidae).
Chitolina RF1, Anjos FA1, Lima TS1, Castro EA1, Costa-Ribeiro MC2.Author informationAbstractThe selection of oviposition sites by females of Aedes (Stegomyia) aegypti is a key factor for the larval survival and egg dispersion and has a direct influence in vector control programs. In this study, we evaluated the aspects of reproductive physiology of Ae. aegypti mosquitoes tested in the presence of raw sewage. Ae. aegypti females were used in oviposition bioassays according to two methodologies: (i) choice assay, in which three oviposition substrates were offered in the same cage: treatment (raw sewage), positive control (distilled water) and negative control (1% sodium hypochlorite) and; (ii) no choice assay, in which only one substrate was available. The physicochemical and microbiological analysis of the raw sewage used in this study indicated virtually no levels of chlorine, low levels of dissolved oxygen and high levels of nitrogenous compounds as well as the presence of Escherichia coli and total fecal coliforms. After 72h of oviposition, the eggs were counted and there was no statistically significant difference (p>0.05) in the oviposition rate between raw sewage and positive control in both methodologies. In addition, females were dissected to evaluate egg-retention and also there were no appreciable differences in egg retention even when raw sewage was the only substrate offered. The data also showed that egg hatching and larvae development occurred normally in the raw sewage. Therefore, the present study suggests that Ae. aegypti can adapt to new sites and lay eggs in polluted water, such as the raw sewage. These findings are of particular importance for the control and surveillance programs against Ae. aegypti in countries where the conditions of poor infrastructure and lack of basic sanitation are still an issue.

Development and Evaluation of an Attractive Self-Marking Ovitrap to Measure Dispersal and Determine Skip Oviposition in Aedes albopictus (Diptera: Culicidae) Field Populations.
Aedes albopictus (Skuse) is a container-breeding species with considerable public health importance. To date, Ae. albopictus oviposition behavior has been assessed in outdoor conditions, but only with laboratory-reared specimens. In outdoor large-cage and field studies, we used an attractive self-marking ovipositional device to assess Ae. albopictus skip oviposition behavior. In field studies, 37 wild Ae. albopictus that visited an attractive self-marking ovisite were subsequently captured at a sticky ovitrap within a 4-d period. Because the average Ae. albopictus gonotrophic period is 4.5-6 d, the wild-caught Ae. albopictus visited at least two oviposition sites within a single gonotrophic period. This provided field-based indirect evidence of skip oviposition. The mean distance traveled (MDT) during the 20-d evaluations ranged from 58 to 78 m. The maximum observed distance traveled was 149 m, which was the outer edge of our trapping ability. As populations of Ae. albopictus increased, the MDT during the 4- and 20-d post-marking period increased significantly. Additional observations of wild-marked and captured Aedes triseriatus (Say) are discussed.

Lethal ovitraps (LO) have been successfully deployed in dengue control operations in north Queensland, Australia since 2004. However, the current plastic-bucket LO must be retrieved before the pesticide-treated strip degrades and the trap begins producing mosquitoes. The logistics involved with trap retrieval are considerable and include recording trap location and retrieval date onto a database, locating and retrieving each trap, and examining lethal ovitraps for eggs. Collectively, these necessary activities greatly reduce the efficiency of dengue control
this next one demonstrates ovitraps work. The dead end ones should be even more effective.

. When sufficient numbers of ovitraps are used and frequently maintained, the vector population can be diminished. One successful example is in Singapore, where ovitraps were used to eliminate mosquitoes at the international airport. Traps have limitations — they require constant supervision and monitoring to prevent them from becoming productive breeding habitats.

OPTIMIZING OVITRAP USE FOR AEDES AEGYPTI IN CAIRNS, QUEENSLAND, AUSTRALIA: EFFECTS OF SOME ABIOTIC FACTORS ON FIELD EFFICACY
ABSTRACT
Insecticide-treated lethal ovitraps are used for control of the dengue vector Aedes aegypti in north Queensland, Australia. In an effort to optimize their use, the influence of deployment height, premise shading, and protection from wind on trap efficacy was assessed in field experiments. Sticky ovitraps were used as a proxy for lethal ovitraps because they provide a direct measure of adult visitation rates. Sticky ovitraps deployed at ground level for 1 wk captured significantly more female Ae. aegypti (mean ± SE, 1.7 ± 0.4) than those set at 1.75-m elevation (1.0 ± 0.3). Setting traps on the leeward side of houses significantly improved collections during a dry season experiment but not in the wet season. Traps set at lightly or heavily shaded premises performed equally well. To determine the optimum number of ovitraps to set per premise, five treatments making up different numbers of traps (1, 2, 4, 6, or 8) were trialled in a Latin square experimental design. Female Ae. aegypticollections increased as more traps were deployed, although mean collections by using 4 (2.6 ± 0.6), 6 (2.4 ± 0.5), or 8 traps (4.8 ± 1.3) could not be separated statistically, suggesting that 4 traps was the optimum number for routine deployment.

The State of the Art of Lethal Oviposition Trap-Based Mass Interventions for Arboviral Control
Abstract:
The intensifying expansion of arboviruses highlights the need for effective invasive Aedes control. While mass-trapping interventions have long been discredited as inefficient compared to insecticide applications, increasing levels of insecticide resistance, and the development of simple affordable traps that target and kill gravid female mosquitoes, show great promise. We summarize the methodologies and outcomes of recent lethal oviposition trap-based mass interventions for suppression of urban Aedes and their associated diseases. The evidence supports the recommendation of mass deployments of oviposition traps to suppress populations of invasive Aedes, although better measures of the effects on disease control are needed. Strategies associated with successful mass-trap deployments include: (1) high coverage (>80%) of the residential areas; (2) pre-intervention and/or parallel source reduction campaigns; (3) direct involvement of community members for economic long-term sustainability; and (4) use of new-generation larger traps (Autocidal Gravid Ovitrap, AGO; Gravid Aedes Trap, GAT) to outcompete remaining water-holding containers. While to the best of our knowledge all published studies so far have been on Ae. aegypti in resource-poor or tropical settings, we propose that mass deployment of lethal oviposition traps can be used for focused cost-effective control of temperate Ae. albopictus pre-empting arboviral epidemics and increasing participation of residents in urban mosquito control.

Comparative Efficiency of Biogents Gravid Aedes Trap, Cdc Autocidal Gravid Ovitrap, and CDC Gravid Trap in Northeastern Florida.
Abstract
We conducted a study to compare the effectiveness of the Biogents Gravid Aedes Trap (BG-GAT) and Centers for Disease Control and Prevention (CDC) Autocidal Gravid Ovitrap (AGO) with that of the CDC Gravid Trap (CDC-GT) (as a standard) for their proficiency to collect mosquitoes in an urban residential neighborhood in northeastern Florida. Aedes aegypti , Ae. albopictus, and Culex quinquefasciatus were collected from each trap, with the latter species being predominant. Significantly more Cx. quinquefasciatus were collected from CDC-GT traps compared with the other 2 traps. Pairwise comparison of the efficiency of the CDC-GT revealed that this trap collected 6.7- to 21.5-fold more mosquitoes than the BG-GAT, depending on species. The BG-GAT collected overall more mosquitoes (3- to 6-fold) than the AGO, with the exception of Ae. aegypti, where both traps were nearly equal in effectiveness.

Impact of Autocidal Gravid Ovitraps on Chikungunya Virus Incidence in Aedes aegypti (Diptera: Culicidae) in Areas With and Without Traps.
Abstract
Published by Oxford University Press on behalf of Entomological Society of America 2016 This work is written by US Government employees and is in the public domain in the US.
Puerto Rico detected the first confirmed case of chikungunya virus (CHIKV) in May 2014 and the virus rapidly spread throughout the island. The invasion of CHIKV allowed us to observe Aedes aegypti (L.) densities, infection rates, and impact of vector control in urban areas using CDC autocidal gravid ovitraps (AGO traps) for mosquito control over several years. Because local mosquitoes can only get the virus from infectious residents, detecting the presence of virus in mosquitoes functions as a proxy for the presence of virus in people. We monitored the incidence of CHIKV in gravid females of Ae. aegypti in four neighborhoods-two with three AGO traps per home in most homes and two nearby neighborhoods without AGO mosquito control traps. Monitoring of mosquito density took place weekly using sentinel AGO traps from June to December 2014. In all, 1,334 pools of female Ae. aegypti (23,329 individuals) were processed by real-time reverse transcription PCR to identify CHIKV and DENV RNA. Density of Ae. aegypti females was 10.5 times lower (91%) in the two areas with AGO control traps during the study. Ten times (90.9%) more CHIKV-positive pools were identified in the nonintervention areas (50/55 pools) than in intervention areas (5/55). We found a significant linear relationship between the number of positive pools and both density of Ae. aegypti and vector index (average number of expected infected mosquitoes per trap per week). Temporal and spatial patterns of positive CHIKV pools suggested limited virus circulation in areas with AGO traps.
