Stop Pests Before They Ever Become a Problem
A recurring Pest Control program gives your home continuous protection against ants, spiders, cockroaches, silverfish, centipedes, earwigs, and more. Exterior barrier treatments handle the prevention, and interior applications are ready whenever activity shows up inside. It works like a year-round guarantee for your property.
Here is how the program works, from first visit to ongoing coverage:
- An initial inspection identifies entry points, harborage areas, and active pest pressure around the home.
- A targeted treatment is applied to the exterior perimeter, foundation, and other high-risk zones to establish a protective barrier.
- Scheduled follow-up visits, on a quarterly or bi-monthly basis, maintain that barrier through every season.
- Interior treatments are performed on request or whenever interior pest activity is reported between visits.
- Free re-service calls are available between scheduled appointments if pests appear before the next visit.

Warning Signs You Have a Pest Problem in Your Home
Most pest problems don't announce themselves. By the time you notice something obvious, insects have often been active inside your walls, under your floors, or around your foundation for a while.
Knowing what to look for early can save you a lot of headache down the road.
Common signs California homeowners notice before calling for help:
- Droppings or shed skins near baseboards, cabinets, or pantry areas
- Unusual rustling or scratching sounds inside walls at night
- Chewed food packaging, cardboard boxes, or stored materials in closets
- Mud tubes or damaged wood along your foundation or crawl space
- Grease marks or smear trails along walls and floor edges
- Musty or unusual odors coming from hidden areas of the home
- Spider webs, egg sacs, or live insects appearing regularly indoors
These are the kinds of clues that tend to get brushed off at first. A spider here, a few ants there. But patterns like these are often early indicators of a larger issue building beneath the surface.
Fenn Termite & Pest Control, Inc. knows that catching these warning signs early is the difference between a quick fix and a costly problem, and that's exactly why a consistent, year-round approach to pest prevention makes so much sense for homeowners who want to stay ahead of it.
