Rodent Exclusion & Sealing in San Bruno — FAQ

How much does rodent exclusion cost?+

A typical home exclusion (10-20 entry points) costs $500-$1,500 including trapping and follow-up. Homes with extensive damage or difficult access (multi-story, tile roofs) may cost $1,500-$3,000+.

Is exclusion better than bait stations?+

Yes. Exclusion is a permanent structural fix that prevents re-entry. Bait stations kill existing rodents but don't prevent new ones from entering. We recommend exclusion first, then bait stations only if needed for severe outdoor populations.

How do rodents get into my attic?+

Roof rats (the most common Sacramento species) enter through gaps as small as a quarter. Common entry points include gaps where the roof meets the fascia, open plumbing vents, A/C line penetrations, and unsealed gable vents.

Will the rodent smell go away?+

If a rodent dies in a wall or attic, the odor typically lasts 2-4 weeks. Sealing the entry points prevents new rodents from entering and dying in the structure. In severe cases, odor-neutralizing treatments can help.
