Find the right help for your spider problem.

Rarely. Of the many spiders that turn up in U.S. homes, only black widows and, where they live, brown recluses have venom that seriously affects people. Everything else is a nuisance at worst, and most are quietly eating flies and other pests.

Mature males are out looking for mates, and your house is in their path. Late summer and fall bring the largest spiders of the year indoors, especially wolf spiders and grass spiders, which end up in tubs they can't climb out of. It passes on its own.

No. Foggers coat every surface in a room, but spiders sit in cracks, corners and voids the fog never reaches. A vacuum, a pole brush and a targeted crack-and-crevice treatment do far more.

Published ranges for a one-time spider service, with inspection, web removal and an exterior perimeter treatment, typically run about $150 to $350. Sealing gaps, repairing screens and confirmed widow or recluse work push the total higher. A good quote lists each part.

Generally yes, with normal precautions. Products go on cracks, voids and exterior surfaces rather than living areas, and your pro should tell you how long to keep everyone off treated spots, usually until they're dry. Mention pets, toddlers or anyone with sensitivities before the visit.

Often not. A vacuum, door sweeps, fewer bugs at the porch light and regular web sweeping handle most of it. Call a pro when a widow or recluse is confirmed, when webs cover the eaves faster than you can safely reach them, or when someone in the house is genuinely distressed.
