How San Bernardino's Mediterranean climate changes Garage Rodent Proofing needs through the year.
Spring rains bring rodents inside looking for sheltered nesting spots. Home entry points become top targets.
Tip: Schedule a garage rodent inspection ahead of the spring rush - sealing entry points now prevents a summer infestation.
Warm, arid warm, dry summers weather sends rodents toward cooler garages. Rodents multiply quickly in the heat.
Tip: Inspect your garage door seals and vent screens monthly - Summer sun may degrade rubber and open gaps.
When temperatures drop, rodents look for heated shelter before winter. It's peak invasion season in San Bernardino.
Tip: Seal foundation and pipe entry gaps before winter - fall is the ideal time to rodent-proof your garage.
Cool, rainy mild, wet winters leaves rodents active all season. Rain pushes them indoors even more.
Tip: After heavy rains, re-inspect your garage seals and screens - Moisture may loosen seals and create new entry points.
“We dealt with mice scurrying through the garage constantly. We called Garage Rodent Defense for a same-day garage mouse removal, and a tech was at our San Bernardino door that afternoon. The crew blocked every gap and set traps - no more mice after that.”
