Springtime Pests:

Ants: As spring brings warmer weather, ants become more active. Common types of ants, like Argentine ants and smelly house ants, can come into your home looking for food. To prevent ant infestations, keep your kitchen clean, seal food containers tightly, and eliminate standing water sources.

Bees and Wasps: Spring also marks the return of stinging insects. Be cautious of beehives and wasp nests in your yard. Keep your trash bins securely closed and avoid leaving sugary drinks or food scraps outside.

Termites: Termites are active year-round in Southern California but can swarm during the spring. Regular termite inspections and maintaining a dry environment in and around your home can help prevent costly damage.

Summer Pests:

Mosquitoes: Southern California’s warm summers create ideal breeding conditions for mosquitoes. Eliminate standing water in your yard, use mosquito repellent, and consider installing screens on doors and windows.

Spiders: While most spiders are harmless, their presence can be unnerving. Keep your home tidy, seal cracks and crevices, and reduce outdoor lighting to minimize the attraction of insects that spiders feed on.

Cockroaches: Cockroaches thrive in warm, humid conditions. Keep your home well-ventilated, fix any plumbing leaks promptly, and store food securely to deter these resilient pests.

Fall Pests:

Rodents: As the weather cools, rodents like mice and rats seek shelter indoors. Seal gaps in your home’s foundation, store food in airtight containers and set traps if necessary.

Spiders (Again): Spiders become more active again in the fall. Perform regular checks for webs and egg sacs, especially in dark and cluttered areas.

Fleas and Ticks: These parasites can infest pets and homes. Flea and tick preventatives should be given to your pets, and you should clean often to get rid of flea eggs and larvae.

Winter Pests:

Rats and Mice: Rodents continue to be a problem during the winter months. Be careful to seal off any possible entry spots, and if you think you might have an issue, you might want to hire a professional pest control service.

Termites: Termites remain active, even in the cooler months. Maintain a termite prevention plan and conduct regular inspections to protect your home.
