Bat Boxes: Help Texas Bats Bounce Back  

Take Care of Texas

While Take Care of Texas focuses on how humans can take action to protect our state, native wildlife also play an essential role in Texas environmental conservation. In celebration of National Bat Appreciation Day on April 17, here are some ways you can help our black-winged neighbors, especially after thousands of bats were harmed or killed by winter storm Uri.  

Bats vacation in Mexico for the warmer winters there before migrating to Texas around February, spending most of their time here in caves and trees. However, they also commonly roost in man-made structures like bridges, buildings, and even abandoned houses. Another way that we Texans can make them feel at home is a comfy bat box where they can reside, safe from predators and the elements! 

What are Bat Boxes? 

Painted Bat Box HouseBat boxes are like birdhouses, just for bats! Also known as bat houses, they come in all shapes and sizes ranging from high-end premade models to do-it-yourself plans. These boxes provide a slim design mimicking the space between bark and a tree trunk, a bat’s ideal nursery. 

Here are a couple of resources from The National Wildlife Federation’s How to Build a Bat House and Bat Conservation International’s Bat House which offer step-by-step plans and tips to build a bat box of your own. 

The ideal location for your bat box: 

  • is NOT attached to a tree (branches shade the boxes, act as flight obstacles for the bats, and as perches for predators), 
  • gets lots of sun (this keeps the box warm and prevents harmful fungus), 
  • is raised at least 15 feet off the ground (to protect against predators and provide easy flight access), and 
  • has a water source nearby (mothers need easy access to water when nursing their pups). 

Nested in the eaves of roofs and buildings or secured to tall poles are all common locations for bat boxes.

Bats: Texas Conservationists 

Bats flying across the skyAccording to Texas Parks and Wildlife Department, “Texas happens to be the battiest state in the country. It is home to 32 of the 47 species of bats found in the United States. Not only does it hold the distinction of having the most kinds of bats, it also boasts the largest known bat colony in the world: Bracken Cave Preserve, near San Antonio, and the largest urban bat colony, Congress Avenue Bridge, in Austin.” 

The Mexican free-tailed bats, our state’s official flying mammal, are the most common bat found throughout Texas. All bats play essential roles in conservation in a variety of ways. 

  • Bats keep crop pests in check, eating up to two-thirds of their body weight in insects each night. Research has demonstrated that these bats can save farmers up to two applications of pesticides per year. 
  • They also serve as plant pollinators for local landscapes. This includes the agave plant used for making tequila, which saw many plants impacted by the winter weather. 
  • In addition to crop pests, bats also eat hundreds of metric tons of mosquitos every year in Texas. This helps prevent the spread of disease to both humans and animals. 
  • Bat guano (bat manure) is an excellent plant fertilizer. Bats fertilize the landscape while they fly around feeding. 

Additional Texas Bat Resources 

“If you happen to find a bat on the ground, DO NOT TOUCH IT! For the safety of the bats and yourself, give the bat space and avoid contact. The bat could be a youngster learning to fly or an ill bat. Wild animals may bite when threatened. Bats, like other mammals, can contract rabies, but the vast majority do not. Please never touch or handle a bat. Notify the site’s manager or volunteer or call a local animal control office.”Texas Parks and Wildlife Department
