How to get rid of this?.To get rid of pest problem under control, inspection is the first and foremost step.
Brown recluse spiders are usually between 6 and 20 millimeters (0.24 and 0.79 in) but may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray. The cephalotorax and abdomen are not necessarily the same color. These spiders usually have markings on the dorsal side of their cephalotorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames fiddleback spider, brown fiddler, or violin spider.
Adult brown recluse spiders often live about one to two years. Each female produces several egg sacs over a period of two to three months, from May to July, with approximately fifty eggs in each sac. The eggs hatch in about one month. The spiderlings take about one year to grow to adulthood. The brown recluse spider is resilient and can tolerate up to six months of extreme drought and scarcity or absence of food. On one occasion, a brown recluse survived in controlled captivity for over five seasons without any food at all.
A brown recluse’s stance on a flat surface is usually with all legs radially extended. When alarmed it may lower its body, withdraw the forward two legs straight rearward into a defensive position, withdraw the rearmost pair of legs into a position for lunging forward, and stand motionless with pedipalps raised.
Brown recluse spiders build asymmetrical (irregular) webs that frequently include a shelter consisting of disorderly thread. They frequently build their webs in woodpiles and sheds, closets, garages, cellars, and other places that are dry and generally undisturbed. When dwelling in human residences they seem to favor cardboard, possibly because it mimics the rotting tree bark which they inhabit naturally. Human-recluse contact often occurs when such isolated spaces are disturbed and the spider feels threatened. Unlike most web weavers, they leave these lairs at night to hunt. Males move around more when hunting than the females, which tend to remain nearer to their webs.
Spiders are generally considered beneficial and most species are not a serious health concern. While all spiders are technically venomous on some level, many lack the ability to pierce the skin. Most species that can bite cause reactions that are less severe than a bee sting. Black Widows which have become increasingly prevalent in recent years are the rare exception. While their bites can cause painful systemic reactions, they rarely lead to death. But always call a Professional for further assistance in treating this kind of pest.
