Sheltering the trap from heavy rain:
A sheltered position (e.g. in a sparse shrub [F10], under a tree or under a roof) has a positive effect on the catch rate. Here even
rainfall does not affect the catch rates.
But if the trap is exposed to heavy rainfall there are negative effects that might decrease the catch rate, even though heavy
rainfall does not damage the trap:
• Mosquitoes avoid heavy rain and prefer sheltered positions. In sheltered positions the catch rate can be therefore higher.
• Heavy rain might disrupt the airflow by clogging the pores of the cover. This causes a reduction in the suction power of the
ventilator. Therefore ensure that the trap is sheltered from rainfall.
If you do not find a naturally sheltered position like trees or shrubs for the trap, it would be best to position the trap under a
covered area, or a self made shelter to keep it out of direct heavy rainfall.
It is important to follow the following guidelines when sheltering the trap from the rain:
• Whatever is placed over the trap must be at least 0.5 meters above the top surface of the trap. Any distance lower will
hinder the visual signals and air currents of the trap and consequently reduce the catch rate.
• Make sure the shelter covers an adequate area around the trap, so that rain cannot enter from the sides.
• Make sure the shelter is stable and durable.
The graphic below [F11] depicts possible locations for the BG-Mosquitaire between mosquito breeding spots, mosquito res-
ting areas, and the house. Please position the trap so that no one can trip over the power cord.
