The great news is that spider control is included in our basic service agreement so there will be no additional charge for you.
Some of the more common Las Vegas spiders include:
Black Widow: These are easy to spot by their sleek, black bodies and the females have the red hourglass marks on the underside of their bellies. They may also be brown in color with yellow areas around the abdomen. They get their name because after mating, the larger female kills the male. A female may produce between four and nine egg sacs each summer with each sac containing three or four hundred eggs. They only take a little over a week to hatch. After laying eggs, the female is hungrier and much more aggressive. Black Widows are one of the most venomous spiders in North America, and are found in every state in the United States. Their bites are serious, but rarely fatal if treated. The female black widow’s venom is a neurotoxin that will attach neurological pathways. If bitten, you may have pain at the site of the bite, aching throughout the body, headache, fever, chills, nausea, vomiting, abdominal pain, delirium, and partial paralysis. Most symptoms disappear in two or three days, but depending on the severity, you may require an anti-venom. These spiders love nooks and crannies and can often be found in the cracks between rocks, in window wells, and any dark areas. Interestingly, a Black Widow’s web is strand for strand stronger than steel.
Desert Recluse: This spider is in the same family as the brown recluse and is often mistaken for one due to its physical likeness. It has a longer leg span, however. They are usually brown and have a dark brown violin-shaped spot on their body. Its legs are light brown with a dark brown to yellow abdomen. Recluses have only six eyes instead of they typical eight for spiders. The recluse is just that, reclusive. It likes to stay hidden away in the darkest, smallest places it can find. Outside, they often live outside in dead plant limbs and can bite when the limb is removed. Inside, people are most commonly bitten in bed, while getting dressed (hiding in clothes or shoes in the closet), or while cleaning out storage areas. Desert Recluse spiders really have no interest in humans unless bothered. If bitten, you will have intense pain and redness within eight hours or so. The site will then form a blister that will burst and leave a deep ulcer. The recluse’s venom is a necrotoxin that kills of healthy cells and prevents the body from removing the dead cells. This can leave a large lesion or ulcer, if damage to the skin is severe, a skin graft can be required. You may also have a fever, rash, nausea, and feel listless. This bite can be fatal, especially in children and elderly.
Camel Spiders, Wind Scorpions, or Sun Spiders are arachnids, but actually are neither scorpion nor spider and contain no venom. They are primarily nocturnal and flee from the sun. They are aggressive and can attack for no reason. Typically though, they aren’t actually interested in you, they just want your shade. They can reach up to six inches and they have large jaws that chop and saw, and they use their digestive fluids to liquefy the victim’s flesh. They are carnivorous and eat other bugs, lizards, small birds and rodents. If you do get bitten, and the bite seems to become infected, you will need to see a medical professional. The bites are painful, but not deadly. They can run up to 10 miles an hour. If you see these monsters around your yard, call a professional and get rid them for good.
