Dangerous Spiders - Spider Control


Spiders with bites that are life-threatening or deadly are the Black Widow and the Brown Recluse. Several people die each year from the bite of these spiders. Emergency medical treatment is necessary if you are bitten by either of these spiders.

The Black Widow is a small, shiny black spider with a red hourglass on the underside of her abdomen. The male is considerably smaller than the female with a body about half an inch long. A Black Widow bite is often immediately painful, and will continue to intensify. Bites can result in damage to the nervous system. Symptoms may include headache, dizziness, shortness of breath, painful abdominal spasms, and back pain. A commercial antidote is available for widow bites, however, children, the elderly and people in poor health are in danger of death from asphyxia. Black Widows typically remain outdoors. They prefer to hide in firewood piles, stacks of boards, under stones and other sheltered or protected sites. Indoors, they frequent attics, crawl spaces, garages and sheds.

The Brown Recluse, also known as a fiddleback or violin spider, can be tan to dark brown. It is about one inch long and has a distinctive darker brown violin-shaped marking on its back, with the neck of the violin pointing away from the head. Venom from the bite of a Brown Recluse can cause extensive tissue damage. Brown Recluse spiders are most active at night. During the day, they seclude themselves in garages, crawlspaces, attics, basements, walls, cabinets, furniture, boxes, or any cracks and crevices they can find. Thus, most people are bitten when they reach into a dark spot where the recluse is hiding. It will be startled and bite as a defensive reaction.

A Brown recluse needs to mate only once to produce eggs for the rest of her life. She can produce 150 or more offspring a year. So, only one recluse can produce an infestation. If you see one, there may be hundreds more hidden in your home. These spiders are difficult to control. They move quickly and are difficult to kill with a vacuum or fly swatter. Since so many may be hidden, spraying parts of your home with store pesticides will not eliminate the infestation. A professional spider control company knows that varied approaches are needed for complete spider extermination.

Other spiders found in the US that are considered dangerous or harmful are the Grass Spider, Wolf Spider, Hobo Spider, and the Saint Andrews Cross spider. Their venom is not as strong as the more well-known varieties, but their bite is painful nonetheless. Additionally, as with all bites, each person may react differently when bitten. For these reasons and the ones outlined above, you may wish to contact a spider exterminator.

If you are bitten while working or enjoying the outdoors, you may never see the spider that bit you. Or its identifying features may be faint or indistinguishable. Even if you have no immediate reaction to a bite, it is best to err on the side of caution and seek medical treatment. If you are bitten by a recluse or widow, it is crucial to seek immediate medical treatment. If spiders start appearing on your property or in your home, contact a spider control company for a professional inspection and recommendations regarding spider extermination.
