How to Pest & Rodent-Proof Your Home or Business Before Heavy Rain Hits Southern California
An atmospheric river of heavy rain is headed toward Southern California, and while most property owners focus on roof leaks and flooding, there’s another major risk that often gets overlooked: pests and rodents seeking shelter.
When rain saturates the ground, rodents, ants, cockroaches, spiders, and other pests are forced out of their outdoor habitats—and straight toward homes and commercial buildings. Now is the best time to take proactive steps to protect your property before infestations start.
At Versa-Tech Pest Management, San Dimas’ trusted local pest control experts, we help homeowners and business owners stay protected before storms arrive.
Why Heavy Rain Leads to Pest & Rodent Problems
Rain disrupts nesting areas and food sources, driving pests indoors where it’s warm, dry, and protected. Common post-rain invaders include:
- Rats and mice escaping flooded burrows
- Ants relocating colonies indoors
- Cockroaches entering through drains and wall voids
- Spiders and other insects seeking higher ground
- Once inside, pests can cause structural damage, contaminate food areas, and create health concerns—especially in commercial properties.
How to Pest-Proof Your Property Before Significant Rain & Downpours
1. Seal Rodent Entry Points
Rodents can squeeze through openings as small as a quarter. Inspect your property for:
- Gaps around doors and windows
- Cracks in foundations or siding
- Utility and pipe entry points
- Seal openings with appropriate materials like steel wool, caulk, or weather stripping.
2. Clear Debris & Vegetation
- Remove clutter that provides shelter close to your building:
- Trim bushes and tree branches away from structures
- Clear leaves from gutters and rooflines
- Remove debris, woodpiles, and stored items from exterior walls
3. Secure Food Sources
- Pests follow food—especially during storms.
- Store food in airtight containers
- Clean up spills immediately
- Use sealed trash bins with tight-fitting lids
This is especially critical for commercial properties, including restaurants, offices, warehouses, and multi-tenant buildings.
4. Check Drains & Moisture Areas
- Standing water attracts pests.
- Ensure outdoor drains flow properly
- Fix leaks under sinks and around HVAC units
- Use drain covers where appropriate
