California is known for its beautiful weather and mild winters. However, there are still seasonal pests that show up during different times of the year. When the seasons change, you might be more likely to see more unwanted critters than you normally would.
Some of the factors that determine how common pests are during certain times of year include:
- Temperature
- Moisture
- Food Scarcity
- Breeding Availability
By knowing which pests are more common during the different seasons, you can be prepared when they show up. Targeting your pest control to specific seasons can be an effective way to prevent issues.
Spring
You will notice more pests in your yard during the spring than you do during other times of the year. This is due to the huge amount of growth that the earth experiences during this time. There is an abundance of food and shelter available, and pests are out in full force.
Ants start to build their colonies in the spring, and this is when you will start to notice them in your yard and around your house.
Fleas use the fact that your pets will be outside more in the spring as an excuse to latch on. During this time, you should check your dogs and cats for fleas much more often.

Summer
Summer in San Diego is a beautiful time, but unfortunately, it is also a very common time for pests. You may find yourself dealing with more insects during picnics and barbecues throughout the summer.
Wasps are a very common summertime pest in California. If you come across a wasp nest, it’s highly recommended to get a professional to remove it.
Termites are out in full force during the summer, and this is when you might start to notice damage to your home.
Fall
San Diego sees many of the same changes in foliage and plant life that other parts of the country do. Pests will use fallen vegetation for food or shelter when the weather starts to change.
Beetles eat rotting vegetation on the ground, which ferments and turns into food. During the fall, you may notice more beetles in your yard or under rocks.
Cockroaches start to move into your home when the weather starts to cool down in San Diego. You may see more cockroaches in your kitchen or cupboards during autumn.
Winter
Winter in San Diego is incredibly mild. However, pests have adapted to the weather and still seek shelter when temperatures drop.
Spiders will weave their winter webs in your home during the winter. You may see more webs near your furnace or around your water heater.
Rodents make their nests for the winter in your walls or behind your furniture. If your house is heated, you may notice rodent droppings around the furnace during this time.
