Stop Pests Before They Ever Become a Problem

A recurring Pest Control program keeps ants, spiders, cockroaches, silverfish, and other common household pests from gaining a foothold in your home. Scheduled exterior treatments build a protective barrier around your property, while interior applications address any activity that slips through between visits. And if pests show up between your regular service dates, a prompt follow-up treatment is included at no extra cost.

Here is how the program works, from first visit to year-round coverage:

  1. An initial inspection identifies active problem areas and entry points around your home.
  2. A targeted treatment is applied to the exterior perimeter, foundation, and key interior zones.
  3. Follow-up visits are scheduled on a quarterly or bi-monthly basis to maintain continuous protection.
  4. Between scheduled visits, any new pest activity triggers a free, rapid-response service call.
  5. Coverage can be adjusted as seasonal pest pressures change throughout the year.

Warning Signs Your Home May Have a Pest Problem

Most pest problems don't announce themselves right away. By the time you notice something obvious, the issue has often been building for a while. Knowing what to look for early can save you from a much bigger headache down the road.

Pests like ants, cockroaches, spiders, and rodents tend to follow the same patterns. They come in through gaps and cracks, settle near food and moisture sources, and multiply quickly in undisturbed areas. The signs they leave behind are easy to overlook if you're not paying attention.

Common signs of a pest problem in California homes include:

  • Droppings or smear marks along baseboards, in cabinets, or near appliances
  • Gnaw marks on food packaging, wiring, or structural materials
  • Shed skins or egg casings in corners, closets, or crawl spaces
  • Live or dead insects appearing regularly indoors, especially in kitchens or bathrooms
  • Unusual odors coming from walls, under sinks, or in enclosed spaces
  • Small entry points like gaps around pipes, door frames, or foundation cracks
  • Rustling or scratching sounds inside walls or ceilings at night

If any of these signs feel familiar, you're not alone. Fenn Termite & Pest Control, Inc. hears from homeowners across the area regularly, and the pattern is almost always the same: a small issue gets noticed, then ignored, then it becomes a real problem. Catching it early makes all the difference.

The service man called by phone about 15 minutes before arrival. He was very polite and very efficient in his work. After inspection, he explained what he did and why he did it. Super service for sure~

We have noticed what we thought might be termite droppings in our attic. We initially called another company which conducted a quick inspection and told us that we needed a full fumigation tenting of our home. Given the high cost and inconvenience, we reached out to Fenn for a second opinion based on their favorable Yelp scores. One of their senior termite specialists Fidel came out and took a much more detailed look at our situation.

Very happy with Fenn! We had a terrible ant infestation with daily home invasions. Drew responded to the quote request within the hour. The pricing is affordable and on par with services rendered. The tech, David was very professional, knowledgeable and friendly. He went above and beyond to prepare the house for treatment. We look forward to working with Fenn and David for our future pest control needs.
