Common Spring Pests in Pasadena, CA

With spring comes warmer weather, blooming gardens, and—sorry to break this to you—a lot more pest activity. The same conditions that make spring pleasant for people also make it pleasant for pests. And they start breeding and feeding and taking over lawns, yards, and homes.

Here’s what you’re likely to deal with as spring arrives in the San Gabriel Valley.

Mosquitoes

Spring is when mosquito populations really take off in Pasadena. Warmer temperatures shake mosquitoes out of their all-too-brief slumber and increased irrigation gives them the perfect breeding conditions. People start watering their yards more, decorative fountains get turned back on, and all that standing water becomes mosquito habitat.

The worst part of all this is that mosquitoes only need a bottle cap’s worth of water to breed. So every planter, birdbath, clogged gutter, and low spot in your yard can become a potential breeding site. So by the time it’s late spring, if you’re not on top of things, mosquito populations can explode.

Ants

Whole colonies start to wake up in the spring, hungry and ready to eat. So they send out scouts to try to find food. You’ll find them trailing into kitchens, bathrooms, and anywhere else they can find moisture and food sources. If you’re really unlucky, you’ll find yourself plagued by smelly Argentine ants that are common in Pasadena.

Spring rains also drive ants indoors since they’re looking for dry shelter. Then when the weather dries out again, they leave in search of water sources. Either way, they’re trying to get in your house and they’re not going to politely knock on the door and bring over cookies or a casserole. Once they establish trails, they’re next-to-impossible to eliminate without addressing the outdoor colonies that keep sending in fresh workers.

Flies & Whiteflies

Warmer spring temperatures mean flies start breeding in earnest. They're attracted to your delicious garbage and appetizing compost, as well as any other organic material they can find in your yard. By the time outdoor dining season begins, flies will try to show up to crash every meal.

Whiteflies go after your spring plants and landscaping. They’ll cluster on ornamental plants and leave sticky honeydew behind that attracts ants and creates messes on outdoor furniture. Once they infest your garden, they’re hard to get rid of without treatment.

Spiders

Spiders become more visible in spring as they emerge from winter hiding spots and start building webs. You'll find them in corners of patios, under eaves, in garages, and around outdoor structures.

While most spiders are harmless, they and their excessive amounts of legs are still unwelcome on your property. And where there are spiders, there are insects they’re feeding on, which means you have multiple overlapping pest problems.

Wasps

Spring is when wasps start building nests. Queens that survived winter emerge and begin establishing new colonies. They're looking for protected spots under eaves, in sheds, around decks, and anywhere they won't be disturbed.

Early spring is the best time to address wasp problems before colonies grow large and aggressive. A small nest in April becomes a major problem by July if you don't deal with it early.

Why Spring Pest Control Matters in Pasadena, CA

The biggest mistake homeowners make is waiting until pests become unbearable before taking action. By the time you see heavy ant trials, find yourself covered in bites, or you run away from a swarm of angry wasps, the populations are already established.

Spring is when you want to get ahead of pest activity. If you treat before populations explode, you’ll spend the rest of your season enjoying outdoor spaces instead of fighting pests.
