Although they often inspire feelings of fear or dread, spiders are beneficial. They prey on other pests, such as aphids, caterpillars, and various insects. The arachnids are typically nocturnal and react to confrontation by fleeing in most cases. Unlike other common pests, spiders are not known to transmit diseases to humans, but they do bite humans if provoked, and the venom of some species is highly toxic. However, the eight-legged arthropods commonly enter homes, where they spin webs and alarm people with their presence. Furthermore, spiders will bite on rare occasions.
How to Get Rid of Spiders
The simplest method of controlling spider infestation is to reduce the pest population (other insects) inside the home so they seek a more dependable food supply outside the home. Control of spiders is best achieved by following an integrated pest management (IPM) approach that involves multiple tactics, such as preventive measures, exclusion, sanitation, and chemicals applied to targeted sites. IPM requires a thorough inspection of the building to locate the pest and its harborages. An inspection should be done at night if the species is nocturnal.
An important first step is to correctly identify the spider, as this determines which management tactics to adopt that take into account specific biology and habits. For example, if the spider is a web builder, control efforts should target its web because that is where this spider spends most of its time. On the other hand, active hunters are spiders that move about widely, and some species are most likely to contact insecticide-treated surfaces at ground level.
Preventing spider bites
Shake out clothing and shoes before getting dressed. Inspect bedding and towels before use. Wear gloves when handling firewood, lumber, and rocks (be sure to inspect the gloves for spiders before putting them on). Remove bedskirts. Move the bed away from the wall. Don’t store boxes and other items underneath beds. Exercise care when handling cardboard boxes (some spiders may inhabit the space under folded cardboard flaps).
