The desert climate of Arizona makes our state an attractive place for wildlife and insects that canโt survive in many other parts of the U.S. Tarantulas are one example. In this post, weโll discuss the types of tarantulas in Arizona, their characteristics and habits, and what you can do about the pests.
About 30 species of tarantulas live in Arizona. The large spiders thrive in the hot, arid conditions of the state and are also present in the desert regions of neighboring states like New Mexico, California, and Nevada.
Tarantulas generally stay hidden, but males do leave their burrows in late summer and early fall to seek mates. When theyโre active above ground, tarantulas may accidentally enter homes and other buildings through gaps, cracks, and open doors and windows. No matter where you live in Arizona, thereโs a chance you may see one of the spiders at some point.
Tarantulas prefer areas with dry soil and hot weather. Theyโre most common in sandy desert and grassland areas. Some species live underground, while others make their homes in trees, caves, cracks in rocks, and agricultural fields. In the northern and higher elevation regions of Arizona, where the climate is cooler and more mountainous, tarantulas are less prevalent.
As previously mentioned, male tarantulas leave their homes in late August through October in search of mates. Technically, the emergence of males isnโt a migration, which is when animals move from one specific area to another at a certain time of year. Tarantulas donโt have a fixed destination when they venture out of their burrows. They will go wherever females are in order to reproduce.
Tarantula mating season happens from late August through October. Youโre most likely to see tarantulas during this period.ย
Although many species of tarantulas exist in Arizona, only a few are common. They include the following species.
The western desert tarantula (Aphonopelma chalcodes) is so common in Arizona that some people refer to the species as the Arizona blonde. They are usually around 2 to 3.8 inches long, with the females being larger than the males. Their nickname comes from the light hairs that cover their bodies.ย
Western desert tarantulas live underground, digging their burrows or moving into abandoned holes made by other animals. Because they are docile creatures, western desert tarantulas are popular pets. In fact, some people try to find these tarantulas in Arizona so they can domesticate them.
At up to 4 inches in size, the Grand Canyon black tarantula (Aphonopelma marxi) is the largest tarantula species. The spiders are so big that they can actually feed on small birds. The tarantulas are predominantly black but have red-brown hairs on their abdomens. Like the western desert tarantula, Grand Canyon black tarantulas tend to live in burrows underground. They usually prefer grassier areas.
The Texas brown tarantula (Aphonopelma hentzi) gets its name from the Lone Star State but is very common in Arizona. Females tend to be around 2 inches wide, while males are slightly smaller at about 1.5 inches in length. Generally, the spiders are dark brown with lighter brown patches of hair on their heads and abdomens. Like the other species discussed, the Texas brown tarantula usually lives underground and may occupy burrows once inhabited by other animals.
Itโs important to note that although they appear intimidating, tarantulas usually arenโt aggressive. They will usually try to flee before attackingโwhen they bite, their venom is unlikely to cause serious health effects in humans. However, the hairs on tarantulas can cause skin irritation.
Although tarantulas are generally harmless, having them around your home or finding them in your house can be alarming. A professional pest control company can help you get rid of tarantulas using proven treatments.
