Spring is a season of warmer days and blooming flowers. But for pests in St. Louis, it’s also the perfect time to wake up and get active. As temperatures rise and rainfall increases, many pests search for food, shelter, and mates. That is why they often end up in homes and backyards. This makes it essential to understand what pests do in spring. Homeowners can protect their space from unwanted visitors if they take St. Louis pest control seriously. Read on to learn about pest activity in spring:
Pests Wake Up from Winter
Ants, wasps, and spiders often go dormant during the winter. When spring arrives, they emerge from wall voids, soil, or basements. Others come out from under outdoor structures. Warmer weather signals the need to find food and expand their colonies.
In addition, mice and rats, which may have spent winter nesting indoors, also become more active in spring. They look for fresh food sources and may increase movement between indoors and outdoors.
Ants Forage
Worker ants search for food to bring back to their colonies as soon as the soil warms. You might see lines of ants in kitchens, in pantries, or along baseboards. In St. Louis, pavement ants and odorous house ants are especially common. These ants are small but determined. If they find crumbs, spilled sugar, or pet food, they will keep coming back. Outdoor nests can also grow rapidly in spring, especially if the weather is moist and mild.
Termite Swarms Begin
Spring is prime time for termite swarms in St. Louis. These swarms happen when winged termites leave their colonies to find a new place to start one of their own. You may spot a sudden cloud of small flying insects near windows, doors, or outdoor lights.
While swarming termites don’t bite or sting, their presence is often a warning sign that there could be a larger infestation nearby. Since termites work silently and feed on wood, they can cause major structural damage.
Stinging Insects Return
Wasps, hornets, and bees begin their seasonal activity in early spring. Queen wasps that survived the winter will build new nests under roof eaves, in sheds, or inside wall voids. Hornets may also return to the same area they nested in the previous year.
Wasps and hornets can be aggressive and dangerous. Their nests grow quickly, so early detection is important.
Mosquitoes Hatch in Standing Water
St. Louis springs are known for their heavy rains, which create a perfect breeding ground for mosquitoes. Any spot where water pools can become a place where mosquitoes lay their eggs. As temperatures rise, these eggs hatch into adult mosquitoes, which feed on blood and can spread West Nile virus. Spring is when their numbers grow, especially in areas with poor drainage or high humidity.
Spiders Seek Food and Shelter
Spiders become more noticeable in spring as they come out to hunt insects that have also become active. While most spiders in St. Louis are harmless, the brown recluse can pose a risk with their venomous bites. Spiders often settle in basements, attics, and garages. This is where they build webs and wait for prey. Their presence usually signals the presence of pests around, serving as a warning that your home might have hidden insect activity.
Rodents Venture Out
Mice and rats may have spent winter nesting indoors. But spring offers more opportunities for them to find food and shelter outdoors. However, this doesn’t mean they will leave your home for good. Rodents move back and forth, especially if they have already found an entry point. In spring, they may chew on new materials and contaminate stored food. Also, they may build nests in sheds, garages, and crawl spaces.
