Springtime is Pest Time in Southern California


Springtime in Southern California signals new beginnings. Seeds sprout, flowers bloom, new creatures are born, and life begins anew. Along with all of this new life comes some more unwelcome activity as critters find their way into your picnics, sporting events, backyards, and within the walls of your home. Let’s take a look at some of the most common springtime critters to watch for as warmer weather seeps into Southern California.


  • Rodents
  • Spiders
  • Bees and Wasps
  • Ants
  • Termites


Rodents can do some major damage if they get into your home. Once rodents get in, they can be difficult to get out as they are winding their way through the walls and into your linen closet and food storage. Once you pull out the camping gear, you may find additional furry families that have wintered with you. Rats can be especially dangerous because they can carry zoonotic diseases, such as hantavirus and leptospirosis.


The most dangerous spiders in the Southern California area include the black widow, the brown widow, and the desert recluse. Avoid bites by wearing shoes outdoors and being careful before putting hands in holes, under furniture, and in woodpiles. Shake out those inner tubes and beach towels to ensure spiders haven’t made them a home during colder months.

Spider infestations can be controlled with a few easy tricks.

  • Keep woodpiles, leaves, and brush away from entryways.
  • Seal cracks around windows and your home’s foundation.
  • Vacuum and sweep storage areas and dark corners to remove webs.

Bees and Wasps

Bees and wasps can wreak havoc on summer picnics and outdoor activities and can quickly turn a nice summer evening sour. Those allergic to bee stings are especially in danger. Exterminating bees and wasps can be difficult as nests can be tucked away in hard-to-reach areas, such as within walls or in attics. If you see an overabundance of bees or wasps near your home, try to find where they are going to and from and call in a professional to remove the nest.


Ants are a common problem in homes where water is readily available. Some of the most populous ants in Southern California include Argentine ants, carpenter ants, red imported fire ants, pavement ants, and Pharaoh ants. Some of these ants can cause painful stings and even carry harmful bacteria into the home.

To prevent ant infestations:

  • Seal cracks around doors and windows and within foundations.
  • Prune away shrubs and branches near the home.
  • Keep floors and surfaces clear of food particles.


Sometimes there’s trouble afoot, and sometimes there’s trouble underfoot.

In Southern California, dry wood termites are the most common home-destroying pest, but subterranean termites can eat homes at almost 80 times the rate of their above-ground brethren. 

Like their name implies, subs live off the moisture in dirt. However, once springtime rolls around (usually between February and May) they seek out wooden structures in which to eat, mate and create colonies. They attack homes from the ground, preferring structures where the wood touches earth, but they’ll find their way into any structure through fissures, crevices, and even through slab foundations.

Subterranean termite infestations are commonly discovered from a network of mud tubes, but they also leave behind other signs, including:

  • Winged Swarmers arriving early in the spring
  • Wings broken off near windows
  • Wood damage
