How to Choose a Pest Control Company in California

A six-step checklist for vetting any pest control provider — before you sign a contract or let anyone spray inside your home.

1

Verify state licensing

Every state licenses structural pest control operators. Before you let anyone spray inside your home, ask for their license number and verify it on your state agriculture department's public lookup. A legitimate company volunteers this information; anyone who dodges the question is a red flag.

2

Ask about insurance and bonding

Licensed pest control companies carry general liability insurance (typically $1M+) and are bonded for work inside your home. Request a certificate of insurance before service. Homeowners insurance rarely covers damage caused by an uninsured contractor working on your property.

3

Get written quotes from at least three companies

Pricing varies widely for identical services. For a general pest treatment, expect $150-$400. For termite work, expect $1,200-$3,500. Quotes more than 40% below the market rate often signal cut corners, expired chemicals, or bait-and-switch upsells during the appointment.

4

Check reviews across multiple sources

Don't rely on Google alone. Cross-check the company on Better Business Bureau, Yelp, and state-level pest control associations. Look for patterns in one-star reviews — repeated complaints about missed appointments, chemical drift to neighbors, or aggressive upselling matter more than a single bad review.

5

Read the guarantee before signing

Legitimate treatments come with a written guarantee: if the pest returns within a defined period (commonly 30-90 days for general pests, 1-5 years for termites), the company retreats at no cost. Read the exclusions. A guarantee that ends the moment you cancel monthly service isn't a guarantee — it's a subscription hook.

6

Ask about integrated pest management (IPM)

Modern licensed companies practice IPM: start with inspection, seal entry points, recommend habitat changes, and use chemicals only where needed. Companies that want to spray everything at maximum strength on the first visit are usually the ones you avoid.
