The “BG-GAT” is a passive trap against egg-laying tiger mosquitoes

Backyard tiger mosquito control with the BG-GAT trap

Biogents BG-GAT (Gravid Aedes Trap) is a low-cost and easy to use tool that can help you reduce the Asian tiger (Aedes albopictus) and yellow fever mosquito (Aedes aegypti) population in your backyard. These species are day active, very aggressive, and can transmit diseases like dengue fever, Zika, and chikungunya. Important for the effectiveness of the trap is to reduce competitive breeding sources.
In comparison to the BG-Mosquitaire trap, it targets a different stage of the mosquitoes: Those mosquitoes that have already bitten and are now searching for a place to lay their eggs which are only a small percentage of those that are host-seeking. Therefore, the BG-GAT catches naturally less mosquitoes than the BG-Mosquitaire.

The big advantage of this trap version is that it is passive, which means it does not require power or supplemental attractants like CO2 or chemical lures. This provides great flexibility in deployment and easiness in handling. Also, especially these females that are targeted with the BG-GAT, can be dangerous, as they might carry a virus and could produce about 50 – 100 descendants.

The BG-GAT uses water and oviposition cues to attract female Asian tiger and yellow fever mosquitoes that are looking for a place to lay their eggs. Once in the trap, the mosquitoes are exposed to a sticky surface and die.

The BG-GAT trap

  • is low-cost
  • easy to set up and deploy
  • needs no power supply
  • does not use pesticides

Its affordability and ease of use make the BG-GAT well-suited for both the individual backyard mosquito control and for neighborhood control programs.
The BG-GATs are available in multiples of 2 or 12.

Principle of function

Female Asian tiger and yellow fever mosquitoes are attracted by water and oviposition cues and enter the transparent chamber through the black funnel. Once in the chamber, mosquitoes try to escape through the translucent windows where they are captured when they contact the surface of the sticky card. The mesh provides a barrier between mosquitoes and the infused water in the lower chamber. The sticky card in the transparent chamber will kill the mosquitoes.

“2 + 1” trap solution

The addition of the highly effective BG-Mosquitaire suction trap to the BG-GATs adds another dimension to your control effort: While the BG-GAT targets mosquitoes that are looking for a place to lay their eggs, the BG-Mosquitaire targets mosquitoes that are seeking for a bloodmeal-host. Therefore, the use of 2 BG-GATs in combination with 1 BG-Mosquitaire is the ideal solution.

2 x BG-GAT

  • low-cost
  • easy to set up and deploy
  • no power supply and attractant required
  • targets mosquitoes that are looking for a place to lay their eggs
  • lower catch rates than the BG-Mosquitaire

1 x BG-Mosquitaire

  • highest catch rates
  • robust
  • easy to set up
  • power supply required
  • targets mosquitoes that are searching for a bloodmeal-host

The set-up and use of the passive BG-GAT trap for collecting gravid tiger mosquitoes

The placement of the mosquito trap is an important factor to ensure high catch rates.
Therefore, it is best to test different locations!

Positioning of the BG-GAT mosquito trapPositioning

A humid, shady, and wind-protected location is very attractive to mosquitoes. Also, the black color of the BG-GAT attracts mosquitoes from some distance. Thus, the trap needs to be placed at a shady, humid place where it is readily visible, but protected from rain.

Effect

For efficient and sustainable mosquito control it is necessary to

  • avoid competition between the BG-GAT trap and other breeding sites. Therefore, remove or empty competing breeding sites, such as flower pots, vases, buckets, water barrels, rain gutters, discarded cups and bottles, and plants that hold small quantities of water.

If the traps are correctly positioned and used continuously throughout the season, they will help to decrease the mosquito population in your backyard.

Features

  • standing trap, made of robust plastic
  • weight: 1.3 lbs / 0.6 kg, dimension: 10.6 x 15.2 in / 27 x 38.5 cm
  • no power supply needed

Components of the mosquito trap BG-GAT

When ordering both the trap and the sticky cards, you get everything you need to begin catching tiger mosquitoes:

Trap: 1 catch bag, 1 funnel, 1 transparent chamber, 1 black bucket, 1 ring, 1 sticky card holder

Sticky cards: A package of 20 pieces

Development
The BG-GAT trap was developed by Dr. A. E. Eiras from the Universidade Federal de Minas Gerais, Belo Horizonte, Brazil, and Dr. S. A. Ritchie from the James Cook University, Cairns, Queensland, Australia. Biogents produces and distributes the trap under a license agreement with both universities.

Examples of areas where traps can be used

  • backyards and gardens
  • outdoor cafés and restaurants
  • hotel outdoor areas
  • campgrounds
  • facilities for outdoor sports and recreation

Placement of traps helps to diminish the local mosquito population when

  • correctly positioned, see “Positioning & effect
  • continuously operated (24 hours a day throughout the mosquito season)
  • operation begins early in the season

“2 + 1” trap solution

The addition of the highly effiective BG-Mosquitaire suction trap to the BG-GATs adds another dimension to your control effort: While the BG-GAT targets mosquitoes that are looking for a place to lay their eggs, the BG-Mosquitaire targets mosquitoes that are seeking for a bloodmeal-host. Therefore, the use of 2 BG-GATs in combination with 1 BG-Mosquitaire is the ideal solution.
