Habitat destruction and modification: Destruction of bat habitat can be attributed to bad agricultural practices such as removal of dead hollow trees, destruction of hedgerows and trees on farmlands. Also destruction of primary forest. Bats rely on these features for roosting, hunting and getting around.
Pesticides Use: Pesticides reduces insect numbers and diversity, and this may have implications for bat populations. It contributes to the continuous decline of bat food which is insects, combined with poisoning incidents in colonies of bats that consume chemically infested preys.
Roost disturbance: Factors that contribute to bat roost disturbances include bat hunting, use of bat caves for religious activities. Also, the removal of larger and older trees, especially hollow trees can deprive bats of valuable roosting sites.
Increasing human population: Most of the threats to bats are directly related to the increasing human population worldwide. An increasing population brings with it extra demands for land, resources, and food, which often results in the degradation or destruction of certain habitat types with a simultaneous effect on bat populations.
