Although Las Vegas is generally hot and dry, the climate appeals to a number of pests. Some pose more of a threat to humans than others.

Common Dangerous Las Vegas Pests

Las Vegas is known worldwide for dazzling resort casinos, gambling and award-winning shows. However, the hot, arid climate is also home to a variety of undesirable pests. The most prevalent and dangerous pests found in and around the city include African honeybees, scorpions and spiders. Specialists with experience at pest control in Las Vegas recommend you seek professional help to deal with any of these invaders.

African Honey Bees

During the 1950s, Brazilian bee researchers introduced African bees in hopes of strengthening European colonies. They were successful. However, the hybrid bees escaped the original colony and migrated to other world areas. By the 1990s, the bees reached the southwestern United States. The bees may create huge nests anywhere within populated areas. The danger lies in the fact that when disturbed, the insects attack in swarms, which leaves victims afflicted with dozens or hundreds of stings.


Scorpions are considered arachnids and related to mites, spiders and ticks. The pests are known to have excellent survival instincts and have been around for thousands of years. Exterminating them requires persistence and time. When temperatures fall, scorpions seek refuge indoors through cracks and crevices. The venom can be life threatening to the very young, the elderly or the ill. Adverse reactions from a sting include breathing difficulty, convulsions, nausea and vomiting along with numbness.


Black widow, the desert recluse and camel spiders are some of the most common but dangerous species found in Las Vegas. Black widows are easily recognized for being black and having the distinct red hourglass pattern on their abdomens. A bite from the small spider often causes abdominal pain, chills, fever, nausea and vomiting along with pain on the bite site. The desert recluse is typically brown with light-colored legs. They have a violin-shaped pattern on their head behind three pairs of eyes. A bite forms a painful bulls-eye pattern, which forms a blister. The wound then opens and leaves an enlarged ulcer. Victims also often experience a low-grade fever, rash, generalized fatigue and nausea. Camel spiders are also known as sun spiders or wind scorpions. However, they are not spiders or scorpions. They are aggressive creatures and have been known to attack unprovoked. Their large, powerful jaws are capable of causing a painful bite, which may draw blood.
