Bats and pest control
A South African pest control company encourages bats to be present in artificial nests on farmland by providing them with the conditions they need (such as nests for growth, hibernation, or rest during night hunting).
Insectivorous bats control pests on agricultural land in two ways:
A brown bat, if kept in a cage, must feed on 25 percent of its weight every night. However, the same mammal with an average weight of 7.9 grams during its lactation should feed 9.9 grams of insects, which is more than their total weight.
This bat can hunt 2080 mosquitoes every night.
Insect behavior change:
The presence of bats in one place has a significant effect on the behavior of insect populations. For example, moths that are able to detect the sounds of bats make fewer mating flights in the presence of bats.
In one study, the presence of bats reduced the damage caused by the willow pest in corn by 50%.
