Most spiders are harmless. In North America, only two spiders have medically significant venom: the black widow and the brown recluse. And even they are not aggressive. They bite only when threatened (usually when pressed against skin).
Spiders are beneficial. They eat insects. Lots of them. Flies, mosquitoes, roaches, ants, moths. A spider in your house is like a free, non-toxic pest control
service.
If you see one spider, it’s not an “infestation.” Spiders are solitary. They don’t colonize like ants or roaches. Seeing a few spiders is normal.
When to call a professional: If you’re seeing multiple black widows or brown recluses, or if you have a genuine phobia that makes home life difficult, call a pest control professional.
