Year-Round Pest Prevention Guide for San Diego Homeowners

Preventing pests is always easier, and cheaper, than eliminating them. In San Diego, where pests are active 12 months a year, consistent preventative habits make a real difference. Here's a practical, season-by-season guide to keeping your home pest-free year-round.

Year-Round Habits (Every Month)

• Store food in airtight containers, including pet food
• Wipe down kitchen counters and stovetop after cooking
• Empty trash cans regularly and keep lids tight
• Fix leaky faucets and pipes, moisture attracts ants, cockroaches, and silverfish
• Keep your home clutter-free, boxes, piles of paper, and stored items provide harborage
• Inspect deliveries, used furniture, and secondhand clothing for bed bugs

Spring (March–May)

Ants & Termites

• Inspect your foundation and entry points for ant trails and seal any cracks
• Apply caulk around windows, doors, and utility penetrations
• Check for termite mud tubes along your foundation and in crawl spaces
• Trim tree branches that touch your roofline, they're ant highways

Summer (June–September)

Mosquitoes, Cockroaches & Fleas

• Empty standing water at least weekly, pots, bird baths, pet bowls, gutters
• Keep grass mowed and vegetation trimmed away from the house
• Check under sinks and around appliances for cockroach activity
• Treat your yard for fleas if you have pets that spend time outside
• Inspect window screens for holes or gaps that let mosquitoes in
• Keep garage doors closed, especially at night

Fall (October–December)

Rodents & Earwigs

• Inspect your roofline, attic vents, and soffits for gaps (a ¼-inch hole is enough for a mouse)
• Trim tree branches away from your roof, roof rats use them as entry points
• Store firewood at least 20 feet from the house and off the ground
• Check garage door seals for gaps along the bottom
• Remove leaf piles and debris from around the foundation

Winter (January–February)

Ants After Rain & Indoor Pests

• Check for ants following rain events, they move indoors to escape wet conditions
• Inspect stored items in attic or garage for signs of rodent activity
• Check mattresses and bedroom furniture for bed bug signs if you've traveled recently
• Check interior plumbing for leaks, cockroaches and silverfish seek moisture in winter
