Tarantula Mating Season Unleashes Arachnid Invasion Across the Southwest
6 Aug
Summary
- Tarantula mating season runs from late summer to fall
- Male tarantulas emerge from burrows to find mates before they die
- Tarantulas are less active during cooler months, spending time dormant in burrows

As of August 6th, 2025, tarantula mating season is in full swing across the Southwestern United States. According to experts, male tarantulas have been emerging from their burrows on a singular mission: to find a female and mate before they die.
These male tarantulas have been alive for five to eight years, and this mating season is their last. Biologists say that during the cooler months, tarantulas are less active, spending time dormant in their burrows to conserve energy and shelter from the harsh environmental conditions.
However, from late summer through fall, the male tarantulas come out in droves, their movements so noticeable that in some areas, it's been described as a "migration." These fist-sized spiders can be found across the Southern and Southwestern states, including Colorado, Missouri, and California.
While tarantulas may seem intimidating, experts assure that they are not aggressive and prefer to avoid confrontation. They are more likely to run away than attack if approached. If a tarantula is found in the home, the best course of action is to trap it in a container and release it outside.
Despite their popularity, there is still much to be learned about these fascinating arachnids. Researchers continue to study their behavior and life cycle, hoping to unravel the mysteries surrounding their seasonal mating rituals.
