I'm having problems with bats. What should I do?

Some people tell me they are having problems with bats living in their attics, dropping feces on their walls, entering their homes or attacking their cattle. That's why I made the section  "Problems". Visit it for guidance on bat problems, and to learn how to live in peace with them.

Are bats poisonous?

  • Bats are not poisonous! The only poisonous mammal is the platypus, which lives in Oceania.

  • However, bats may transmit diseases to people, especially rabies and histoplasmosis. But all wild animals may be sources of diseases.

Vampire bats (family Phyllostomidae, subfamily Desmodontinae) may attack people sometimes, but their preferred prey are cattle (bovine, ovive, suine) or large wild animals (bores, horses, tapirs, monkeys).

What do bats eat?

Bats are the group of mammals with the most diverse diet. They feed on insects, small vertebrates (frogs, fishes, rats, birds), fruits, seeds, leaves, nectar, pollen and blood. Species vary from high specialization on one kind of food to an omnivorous diet.

Where do bats live?

Bats have day roosts, where they sleep, form colonies and spend most of their time, and night roosts, where they eat food. As day roosts, bats may use caves, rock crevices, hollow trees, tree barks, large leaves (e.g. palms), holes in the ground, and human constructions, like attics and bridges.

Why do bats sleep upside down?

Probably, most bats sleep and hang upside down, because they descend from quadruped ancestors (shrews and hedgehogs). So, during the course of their evolution, they invested a lot in transforming arms into wings, and legs were left behind and became weak. Following another evolutionary path, birds descend from biped ancestors (a group of dinosaurs), so their legs were already strong and were kept this way.

To how many pups do bats give birth at the same time?

Almost all bats give birth to only one pup at a time, but some may have two pups, and only a few may have up to four pups.

How long does a bat live?

Considering their small size, bats are the most long-lived mammals. Some small species of the genus Carollia, for instance, may live 15 years in the wild (Fleming 1988). Some species of Vespertilionidae may live more than 30 years (Barclay et al. 2004). And the world record is held by one individual of the species Myotis brandtii, which lived 38 years (Khiritankov & Ovodov 2001)!

Which is the largest bat of the world? And the smallest?

According to Nowak (1994), the largest bat of the world is the flying-fox Pteropus vampyrus, with a wingspan of 1.7m and occuring in Asia. However, Kunz & Jones (2000) say that this species may reach only 1.5m of wingspan, and they also say that maybe individuals of the species Acerodon jubatus may be larger and heavier. The smallest bat on earth, which is also the smallest mammal, is Craseonycteris tonglongyaii from Thailand, weighting only 1g.

At what speed do bats fly?

Flight speed depends on the species. Some records made by Bat Conservation International  point out that Tadarida brasiliensis may fly at speeds of 96km/h, and is probably one of the fastest bat species.
