But that's not the whole picture. Brown recluse and black widow spiders present real venom risk. Large infestations in basements, garages, and crawl spaces become genuinely problematic. And for plenty of homeowners, spider presence — regardless of species — is simply not acceptable.
Canady's spider pest control service addresses all of it: species assessment, targeted treatment, de-webbing, and prevention. No drama, no overclaiming. Just professional service that works.
Comprehensive spider control tailored to your specific situation.
We identify common house spiders, wolf spiders, cellar spiders, brown recluse, black widow and others to determine the right approach.
Removal of established webs, egg sacs, and harborage sites in basements, garages, eaves, and more.
Targeted application along foundations, entry points, and insect travel zones to reduce spiders and their prey.
Treatment of common spider population centers in undisturbed areas of Portola Valley homes.
Quarterly exterior treatments timed to seasonal spider activity for consistent low pressure.
Spiders follow food. Wherever insects are abundant — near outdoor lighting, around windows, in damp basements — spider populations concentrate.
We assess both the spiders and the conditions driving their presence for lasting results.
