The warm weather and the rain might mean a hot tarantula summer in Houston. Yikes! But seriously, did you know tarantulas are spotted more in Texas between May and August than other times in the year? So, why is that, and what should you do if you spot a tarantula?

More Tarantulas Spotted In The Summer

During this time of year, male tarantulas are migrating to search for females to mate with. Tarantulas are also known to appear during warmer months and after a decent amount of rainfall. Instead of spinning a web, these tarantulas usually take over burrows from insects or rodents and then line them with their silk. They enjoy eating insects like crickets and roaches, but can also devour small lizards and mice. Male tarantulas live up to only eight years, but female tarantulas can live up to 25 years or more.

What Should You Do If You Spot a Tarantula?

If you see a tarantula on your next walk or at a state park, don’t try to touch it. Leave it alone! Texas tan tarantulas are usually not aggressive and non-venomous to humans, but they can still bite you if provoked. The bite can be similar to getting a bee sting, so you want to be careful.
