Your Guide to Warm Weather Pest Problems and How to Keep Them Out

Summer brings longer days, warmer temperatures, and unfortunately, a surge in pest activity. As homeowners enjoy backyard barbecues and open windows, many pests take full advantage of the seasonal conditions to invade homes, yards, and outdoor spaces.

So, what pests are most common in summer, and what can you do to stop them? In this post, we’ll cover the top summer pests, why they thrive during the warmer months, and how to keep your home protected.


Why Pests Are More Active in Summer

Most pests are cold blooded, meaning they thrive in warm environments. Summer provides the perfect breeding conditions for many insects and rodents due to increased heat, humidity, and readily available food and water sources. From stinging insects to ants and mosquitoes, summer is their peak season.


Top 7 Most Common Summer Pests

1. Ants

Ants are one of the most noticeable summer pests, frequently seen marching in lines across patios, sidewalks, and kitchen counters.

  • Why they’re common: Summer heat speeds up their metabolism and breeding cycles.
  • Prevention tips: Keep food sealed, clean up crumbs, and seal entry points. Treat outdoor nests early before they expand indoors.


2. Mosquitoes

Mosquitoes are not only annoying, they can also spread serious diseases like West Nile virus and Zika.

  • Why they’re common: Mosquitoes breed in standing water and thrive in warm, humid weather.
  • Prevention tips: Eliminate stagnant water, install window screens, and use repellents or professional yard treatments.


3. Flies

Houseflies, fruit flies, and gnats multiply rapidly in summer and are drawn to food and garbage.

  • Why they’re common: Warmth accelerates breeding; uncovered food and waste attract them.
  • Prevention tips: Seal garbage, clean up food spills, and maintain compost bins properly.


4. Wasps and Yellowjackets

Stinging insects like wasps, hornets, and yellowjackets are more aggressive in summer.

  • Why they’re common: Nests are in full swing by mid summer, and these pests become territorial.
  • Prevention tips: Avoid sweet drinks outdoors, keep trash covered, and treat or remove nests early.


5. Spiders

While spiders themselves aren’t as dangerous as other pests, they become more visible in summer while hunting for prey.

  • Why they’re common: Summer brings more insects, giving spiders plenty of food.
  • Prevention tips: Clear webs regularly, reduce insect activity in your home, and seal up hiding spots.


6. Fleas and Ticks

If you have pets or spend time outdoors, fleas and ticks are a real concern in summer.

  • Why they’re common: Tall grass, heat, and humidity provide ideal conditions for these pests.
  • Prevention tips: Treat pets regularly, mow your lawn, and wear protective clothing in wooded areas.


7. Cockroaches

Roaches are resilient pests that can become more active indoors during summer to escape extreme heat.

  • Why they’re common: Summer offers moisture and easy access to food in kitchens and bathrooms.
  • Prevention tips: Fix leaks, keep areas dry, and clean thoroughly, especially behind appliances.
