Texas is no stranger to creepy crawlers, but this one harbors a whole new level of danger. Asps are the most toxic caterpillars in North America, and they’re infiltrating one major city in the Lone Star State.

Puss moth caterpillars, more commonly known as asps, are the most toxic caterpillar in North America.

Wikipedia They are native to the Southern U.S. and live in trees and shrubbery, typically surrounding residential areas.

Because of their long, silky hair, asps resemble a ball of cotton.

Wikipedia They often go unnoticed for long periods of time as a result.

Mating occurs twice a year, and populations peak in both spring and fall.

Wikipedia Body color can be yellow, gray, or reddish-brown, and venom is stored in the hair.

The deceiving critters aren’t multiplying for no reason. A well-intended effort to preserve vegetation in the Texas Medical Center area served as a catalyst to the outbreak.

Flickr/PINKE Nets were placed around the trees in an effort to keep birds out. This allowed the asps to flourish in the absence of predators. Researchers have documented over a 7,000% increase compared to other parts of Houston!

Most of the time, asp bites cause nothing more than localized pain, burning, and redness.

Upon being bitten, immediately place an ice pack on the bite. Oral antihistamines may also be taken for the itching and burning. Keep a close eye out for any serious symptoms and call 911 if necessary.
