Recent research from several studies has found that spider bites are usually not what you think they are. Only 3.8 percent of reported spider bites are, in fact, spider bites. This is good news for those who live of fear of spiders. However, people who live in areas where widow and recluse classes of spiders are native should still be cautious.
According to Chris Buddle, an arachnologist from McGill University in Montreal, most “spider bites” are most likely to be:
- Bites or stings from other insects, such as fleas,
- Skin reactions to chemicals, or
- Skin reactions from infections.
There are two groups of spiders which do commonly bite humans: the widow group, which includes black widows, and the recluse group, which includes brown recluse spiders. Both black widows and brown recluse spiders are native in New Mexico so residents should know how to identify them, and take simple precautions like not reaching into or entering small crawl spaces without first checking
Black widows spiders are black with a red “hourglass” shape on their backs. They are ¾ to 3/8 inches in length. Black widows spin webs near ground level, in protected areas such as in boxes or woodpiles, under eaves or other areas where they will not be disturbed. A bite from a black widow causes severe pain, and children and the elderly are at the greatest risk of a serious reaction to a bite.
Brown recluse spiders are usually about ¼ to ¾ inches in size, but they may grow larger. They are typically light to medium brown, but they range in color from cream-colored to dark brown or blackish gray. They build asymmetrical webs that frequently include a shelter made of disorderly thread. Brown recluse spiders build their webs in woodpiles and sheds, closets, garages, crawl spaces, and other places that are dry and generally undisturbed. In side homes, they favor cardboard, inside shoes and dressers, in bed sheets of unused beds, in clothes stacked or piled or left lying on the floor, inside work gloves, and behind baseboards and pictures.
It is best to spray year-round for spiders to keep their presence at a minimum. Pest Defense Solutions can help you address problems with spiders, as well as other common New Mexico inspects.
