The United States is home to hundreds of spider species. Though black widows and brown recluse spiders (also known as violin spiders) are two exceptions, very few spiders endanger humans. Spider diets consist largely of live insects, including many common garden pests. But when spiders make their way indoors or surprise family and friends on your patio they disrupt households nonetheless.

Spider Identification: Spiders belong to a category of creatures known as arachnids, which includes ticks and scorpions, but not insects. Adult spiders range from pinhead size to several inches across, with colors and markings as varied as their sizes. While insects have six legs and three main body parts, spiders have eight legs and two primary body parts. Immature "spiderlings" hatch from egg sacs as small versions of adults.

Signs/Damage of Spiders: Spiders don't damage plants, so they're less obvious than insect pests. Some types spin insect-catching webs in intricate patterns or irregular cobwebs, but others forgo webs and hunt their prey instead. Often, the only sure sign of a spider infestation is seeing them in or around your home. They're often found in dark, moist hiding places that draw insects near.

How to Control Spiders: Large spider populations indicate other pest issues. Spiders go where their food source is plentiful, so managing insect pests is essential to control. Effective treatment targets spiders and the insects they eat before they make their way indoors.
