Important: A location under a bush is a very good position, since mosquitoes rest under the leaves. However, please pay at-
tention that the trap and all its upper surfaces are clearly visible to patrolling mosquitoes, so that its specialized appearance
is effective in attracting the mosquitoes. Therefore do not place the trap under very dense bushes [F14]. A distance of at least
0.5 meters above the top of the trap needs to be kept clear [F15]. Any distance lower will hinder the visual signals and air
currents of the trap, and consequently reduce the catch rate.
•
Keep the trap out of direct sunlight, since mosquitoes avoid the sun.
•
Protect the trap from the wind. Winds not only deter the mosquitoes, but can also affect the suction from the ventilator
decreasing the catch rate.
•
Sheltering the trap from heavy rain:
A sheltered position (e.g., in a sparse shrub [F15], under a tree, or under a roof) has a positive effect on the catch rate. Here
even rainfall does not affect the catch rates.
However, 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 rain and prefer sheltered positions. In sheltered positions, the catch rate can be therefore higher.
•
Rain clogs the pores of the cover which leads to a reduction of the suction power.
•
Other animals such as snails are attracted by a wet trap and tend to creep into the trap.
If you do not find a naturally sheltered position for the trap, it would be best to position the trap under a roofed area or a
self-made shelter to keep it out of direct rainfall.
Best results will be obtained by following these guidelines when sheltering a trap from rain:
•
Always leave an unobstructed space of approximately 0.5 meters above the trap opening. 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.
