In Florida, the Mexican Redrump Tarantula (Brachypelma vagans) has established a population, particularly in South Florida’s citrus groves. First identified in 1996, this species has been noted for its rapid spread in the area, thriving in overgrown regions near swamps and canals. 

The tarantula is mostly black with reddish hairs on its abdomen and can grow to a leg span of approximately 5 inches. While their venom is not life-threatening to humans, it can cause painful bites, and they may pose a threat to small pets and wildlife.(ref)

2. Texas

Texas is home to several tarantula species, with the Texas Brown Tarantula (Aphonopelma hentzi) being the most common.(ref) This species can be found throughout the state, particularly in grasslands and rocky areas. 

They are known for their large size, with leg spans exceeding 4 inches. The mating season occurs from May to August, during which males are particularly active in search of females.
