As the days grow shorter and the temperatures begin to drop, fall brings a unique set of challenges for homeowners in Central California. While the changing leaves and cooler weather can be a welcome relief, they also signal the arrival of certain pests seeking shelter and sustenance. In this blog post, we'll explore some of the common pests to watch out for this fall in Central California and offer tips on how to protect your home.

Seasonal Pests to Watch For This Fall


As the weather turns cooler, rodents like mice and rats start seeking refuge indoors. They can enter through small cracks and openings, making your home their warm and cozy nesting ground. Not only can they cause structural damage, but they also pose health risks through the spread of diseases.

To prevent rodent infestations, seal any potential entry points, keep food stored in airtight containers, and consider setting up traps in strategic locations. Regularly inspect your home for signs of rodent activity, such as droppings or gnaw marks.


Fall is a prime time for ants to forage for food in preparation for winter. They can infiltrate your home in search of sweets, proteins, and water sources. Common types in Central California include Argentine ants and odorous house ants.

To deter ants, keep your kitchen clean, wipe down surfaces regularly, and promptly fix any leaks or standing water. Additionally, seal cracks and crevices around windows, doors, and the foundation to prevent entry.


While most spiders are harmless, some varieties like black widows and brown recluses can pose a threat to humans. They seek shelter indoors during the fall months, making it important to be vigilant.

To reduce the likelihood of spider infestations, keep your home clutter-free, vacuum regularly, and seal cracks and gaps in windows, doors, and walls. Consider using natural deterrents like peppermint oil, which spiders dislike.


Cockroaches thrive in warm, humid environments and are known to be active year-round in Central California. However, they may become more noticeable in the fall as they seek food and shelter.

To keep cockroaches at bay, eliminate food and water sources, fix any leaks, and seal cracks and gaps around your home. Using baits and traps can also help control their population.

Stinging Insects:

Wasps, hornets, and yellow jackets can become more aggressive in the fall as their natural food sources become scarce. They may build nests in or around your home, posing a threat to your family and pets.

To minimize encounters with stinging insects, inspect your property for nests, and remove any fallen fruit or other food sources that may attract them. If you discover a nest, it's best to contact a professional pest control service for safe removal.
