Funnel Spider Webs in Junipers: Beneficial, Not a Problem

Hundreds of funnel webs in junipers = recent spider hatch. Spiderlings build webs immediately to catch first meals. Most die; survivors control spider mites and other juniper pests.

Why So Many?

One egg sac = dozens of spiderlings. High mortality—birds, cannibalism, starvation. Within weeks, only a few territorial adults remain.

Verdict

Leave them alone. They're free pest control. Funnel weavers (Agelenidae) are harmless to humans/pets. No treatment needed or recommended.
