Why & How Pests Change With Each Season in Perrysburg, OH

As seasons move through their yearly cycle, the types of pests plaguing Perrysburg change, too. From the first sign of spring warmth to the deepest winter chill, each time of year brings its own wave of unwanted guests. At Mosquito Squad Plus, we’ve developed an arsenal of pest control solutions that are designed to respond to the ever-changing needs of Perrysburg residents.

Spring = The Big Thaw

Spring in Perrysburg is symbolized by rebirth, and just as flowers begin to bloom and baby chicks begin to hatch, so do pests begin to come out of dormancy. For this reason, springtime is ideal for implementing early intervention strategies. Beginning in March and lasting through the season, you’re likely to witness some of the following springtime pest behaviors:

  • Mosquitoes become a common sight once temperatures begin reaching 50°F.
  • Ticks return to high grass and brush, where they’ll wait for their next host. Ticks remain active most of the year, but spring is when they begin to peak.
  • Fleas begin reproducing again, especially as household pets become more active outdoors, as does wildlife that may have spent the winter hibernating.
  • Boxelder bugs that spent winter in sheltered areas may emerge on warm spring days.
  • Spiders begin feeding on the surge of other pests, so you’ll see them around more often, too.

Summer = Under Siege by Swarms

Summer’s heat and long, sunny days create the perfect conditions for pests to thrive. During the summer, most pests’ breeding habits will accelerate, and some pests will become increasingly more aggressive.

  • Mosquito activity is at its height, and is especially a problem anywhere they can find access to standing water, such as in overwatered lawns, puddles, and clogged gutters.
  • Ticks thrive in the dense vegetation that grows lush in the summer, and you and your pets are at a high risk of exposure to the diseases they carry. (Always perform a tick check after spending time outdoors!)
  • Heat helps to accelerate flea reproduction, and more fleas mean more itching.
  • Gnats come out in full force, either to gobble up the fungus that grows naturally around plants in your garden bed, or to feast on any organic material that builds up in your drains.
  • Wasps become more fiercely defensive of their nests, especially in late summer. Yellow jackets and hornets may also become a bigger issue.

Fall = Time for the Great Indoors

As temperatures drop, pests prepare to overwinter by moving indoors or building up their populations for the final time before winter.

  • Mosquito numbers may taper off, but sunny afternoons can still bring out stragglers. They won’t be fully gone for the year until the temperature consistently stays below 50°F.
  • Ticks will remain active outdoors until the first hard frost. Holidays like Thanksgiving often mean booked weekends at the dog kennel, where ticks thrive indoors all year long.
  • Ants increase activity as they seek to build reserves before winter – Aesop’s fable about the ants and the grasshopper wasn’t far off from the truth!
  • Boxelder bugs and stink bugs begin clustering on sunny walls and windows as they look for entry points into homes.

Winter = “Snug as a Bug”

Many pests spend the winter months hibernating, while still others find a way to overwinter indoors.

  • Spiders tend to stay active indoors where they can feed on other pests.
  • Invasive species like stink bugs, Asian beetles, and elm seed bugs flock indoors where they’ll hang out in sunlit spaces through winter.
  • Winter is also a useful time to check screens, cracks, gaps, and other potential pest entry points while preparing for the next spring surge.
