Severe Spider Infestation: Professional Kit or Pro Service

Arachnophobe with large black fuzzy spiders in garage—OTC sprays fail. Spider Elimination Kit (pestproducts.com) treats inside/outside + habitat removal.

Better Option

Hire a licensed pest control company. They guarantee results, have pro-grade products, and treat attics, crawlspaces, wall voids you can't reach.

DIY Kit

If self-treating, follow kit instructions meticulously: perimeter spray, crack/crevice dust, web removal, clutter reduction.

Large spiders likely wolf spiders or grass spiders—beneficial but unsettling.
