Is it a Good Idea to Poison a Bat?

Having a bat colony in your house can be frustrating. I understand that! But no matter what you do, NEVER poison a bat. Why waste the life of this incredible and important creature, if there are other 100 percent effective means of dealing with the problem. Not convinced? Here are five reasons you shouldn’t poison a bat.


Some bat species in the United States are protected under the Endangered Species Act (ESA) because they are a threatened species. This means that it is illegal to injure, let alone kill them. Like U.S. federal law, bat habitats are also protected. Violators are subject to hefty fines and up to 6 months in prison.

Bat Poison


Here’s the thing, there are no registered or manufactured poisons designed to kill bats. Even if there were, good luck giving bats the poison. Bats eat insects, but if you poison the insect, they’ll die. That’s why some people make use of insecticides instead. Unfortunately, it doesn’t kill most of them (bats are not bugs!). However, a few types of spray fumigants may kill bats in high doses. But they also place humans and pets at risk.


Take one moment to think about what happens when you poison an animal. The poison slowly begins to damage the internal organs, resulting in internal bleeding. It undergoes immense pain and discomfort before it finally dies. That’s why wildlife experts discourage the use of poisons on animals. Moreover, bats are great animals that can live for more than 15 years. By killing a colony, you’re essentially wiping out thousands of years of life. It’s simply inhumane!

Finding the Dead Bats

Let’s assume there was a legal and safe poison that could humanely kill bats, which is not the case. But if it were true, how would you find the carcass? When an animal is poisoned, it normally resides in a hidden spot to die off in peace. Locating this animal is usually difficult. It isn’t until the body starts to decay and give off a strong and unpleasant smell can you be able to trace it. In some cases, it may be inaccessible locations like inside the walls, which makes the removal process more complicated. Now, imagine you have a colony consisting of 100 bats. That same problem is multiplied by 100. By using bat poison, you’ll end up with a problem bigger than the one you started with.

Exclusion: A Better Alternative

Exclusion is a better way to deal with the problem. First, all potential entry holes are located and sealed, except one. In this hole, an exclusion device is installed. This device allows the bats to leave your attic but it prevents them from getting back in. Once all of them have been excluded, you can remove the device and seal off the last hole. Thereafter, the infected space can be decontaminated.


Poisons do NOT work. They are illegal, ineffective, and inhumane, so stay away from them. Bats are crucial to the ecosystem as they help to keep the insect population in check and assist with pollination. Therefore, it’s beneficial to have them around. Remember, poisoning or killing bats is not the way to go.
