As temperatures get hot this summer, pest experts are warning homeowners to prepare for a noticeable increase in insect activity as higher temperatures accelerate breeding cycles and drive many pests closer to people, homes and outdoor gatherings.
“When temperatures climb into the upper 90s and around 100 degrees, insects don’t slow down—they speed up,” said a spokesperson for JP McHale Pest Management. “Heat accelerates their life cycles, so homeowners can expect to see more mosquitoes, ants, flies and stinging insects.”
The combination of soaring temperatures, backyard barbecues, outdoor celebrations and increased food waste creates ideal conditions for pests to thrive.
“The Fourth of July creates the perfect storm for pests,” the spokesperson said. “Backyard barbecues, overflowing garbage, sugary drinks and people spending more time outdoors all provide food sources and opportunities for insects to thrive.”
Ants are among the most common summertime invaders, often moving indoors during hot, dry weather in search of water. Kitchens, bathrooms and basements are frequent targets. Mosquitoes are expected to become more active around standing water found in buckets, flower pots, birdbaths and clogged gutters where they lay eggs.
Flies are attracted to garbage, food scraps and sugary beverages, while wasps, yellowjackets and hornets become increasingly aggressive around picnics and cookouts where protein and sweet foods are abundant. Spotted lanternflies also remain active, feeding on trees and ornamental plants while leaving behind sticky residue that attracts additional pests.
Extreme heat can also stress lawns, trees and shrubs, making landscapes more vulnerable to insect damage.
“Extreme heat doesn’t just affect people and pets—it stresses lawns, trees and shrubs as well,” the spokesperson said. “Weakened landscapes are more susceptible to insect damage, making proper watering and maintenance especially important during heat waves.”
Experts also recommend watching for carpenter ants, termites and rodents, which can become more active during prolonged hot weather.
“Preventing pests is much easier than eliminating an infestation after it starts,” the spokesperson said. “Simple steps like eliminating standing water, sealing trash cans, cleaning up food spills, trimming vegetation and sealing entry points around the home can make a significant difference.”
