Management tactics on this page are those discussed in the Pest Notes series, published by the University of California Statewide Integrated Pest Management Program (UCIPM). Information on this page alone is not sufficient for making pest management decisions. For detailed management recommendations, see the associated UCIPM Pest Note. Each tactic is also linked back to the appropriate Pest Note section.

The risk posed by any pesticide product is determined both by toxicity and level of exposure. Information presented on these pages is not intended to constitute a full risk assessment. Information is provided here only on active ingredients, not on inert ingredients. The active ingredient is generally-but not always-considered to be the most hazardous ingredient of a pesticide preparation.

POTENTIAL CONSEQUENCES OF NOT TREATING - What's this? • Most spiders are beneficial and cannot harm people. Most have fangs too small to penetrate human skin. • Bites might cause no reaction at all, or might result in varying amounts of itching, redness, stiffness, swelling, and pain¿at worst, usually no more severe than a bee sting. • The bite of the black widow spider, Latrodectus hesperus, can cause mild to painful and serious reactions, but death is very unlikely. Small children, the elderly, and persons with health problems are likely to suffer more severe consequences.
