As the sun sets in the evening, you may have seen bats swooping low in your yard. Whether or not you like bats doesn’t really matter- they are out there and as long as they stay out of your hair, hopefully you won’t have to deal with them! But there are some pros and cons with having bats on your property. Here are some of the pros and cons of bats in your backyard.

  • Bats are natures insect control. They eat mosquitoes all night long, also binging on moths, wasps, beetles, gnats, midges, mayflies and other insects. The little brown bat is one of the most common bats in North America and these insectivores can catch up to 600 insects an hour!

  • Guano, which is another name for bat droppings, can be beneficial for your garden! Guano is rich in nitrogen and is considered an excellent fertilizer. There are even some enzymes in bacteria in guano that scientists have found to be good when added to cleaning agents, including laundry soaps (we’ll leave that to the scientists to keep testing).

  • Bats are pollinators. They move pollen grains from flower to flower, which helps to pollinate flowers and plants.

  • Bats help distribute the seeds of many different kinds of plants, including bananas, mangoes, cashews, dates, avocados, peaches and figs, just to name a few.

  • Bats may take up residence in your home to raise their young. When they do this, they become a problem on your property, causing damage to your structure and leaving bat droppings throughout your attic and on your home.

  • Although not typical, bats can spread rabies. This disease can be dangerous for you and for your pets. They are not usually aggressive mammals, but may bite if manhandled.

  • Bat guano can spread histoplasmosis. This illness primarily affects the lungs; it is spread by breathing in a fungus that grows in accumulated guano.



Although bats can be useful, they are best when they stay away from your home and attic! If you have bats in your home, you don’t want to try to evict them on your own. There are laws about when you can evict bats, especially if they are roosting with their young. To get rid of bats and help prevent them from returning, contact your local pest control professionals. When it comes to bats and other wildlife animals, it is always best left to the pros!
