Large Numbers Of Tarantulas Are Invading Residential Areas

When tarantulas are found within homes they are usually being kept as pets, but during the summer season, the southwest United States becomes overrun with swarms of male tarantulas looking for mates. These annual migrations sometimes bring tatrantuals into homes in California, Arizona, New Mexico and Texas. Tarantula migrations draw tourists to certain hotspots in the southwest where the arachnids are expected to be found moving in enormous masses numbering into the thousands. Once male tarantulas find a female burrowing within the ground, up to 1,000 eggs are produced, so while tarantulas may be hated by arachnophobes in Texas, the eight-legged critters are not going anywhere.

Tarantula migrations occur all summer, but the largest migrating masses occur during July in north Texas, and thousands are likely traversing through populated residential areas right now in the state. The Mexican redknee tarantula is considered one of the most commonly encountered tarantula species in Texas, and they can sometimes wander into homes. Another common species in the state, the Texas brown tarantula, is notably large in size and particularly heavy, as females often weigh in excess of 3 ounces. Females of this species are docile and prefer to remain in their burrows, but during mating season, which lasts from May until October, females may leave their burrows and make contact with humans.

While tarantulas may be intimidating to look at, they are largely harmless to humans, but those looking to avoid tarantula encounters during mating season in Texas should be mindful around bushes where the spiders are often located, and keeping an eye on city streets is also wise, as hoards of tarantulas regularly travel through urban areas. Tarantulas can inflict venomous bites, but these bites almost never require medical attention, and the stinging sensation caused by tarantula bites are comparable to bee stings. However, some residents cannot stand the sight of tarantulas, and if this should be the case, yards can be treated to prevent tarantulas from invading properties.

Have you ever encountered a tarantula on your property?
