West Central Minnesota Pest Calendar

Month-by-Month Guide to Pests in Minnesota

At Braness Pest Control, we understand that Minnesota’s changing seasons bring more than shifts in weather. Each season comes with its own set of common pests — from carpenter ants in the spring to rodents in the winter.

Use this pest calendar to learn which pests are most active each season, the risks they pose, and how to keep your home protected year-round.

Spring

March – May

As temperatures rise and warm weather returns, pests emerge during the spring in search of food sources, moisture, and shelter.

Active Pests in West Central Minnesota

  • Ants (especially carpenter ants)
  • Spiders
  • Flies
  • Mites
  • Springtails
  • Earwigs

Why These Pests Emerge

Melting snow and spring rains create damp areas around foundations and basements, which are ideal for pest activity.

Ants begin exploring for food, spiders move indoors, and earwigs hide in leaf litter, soil, and wood piles.

Braness Prevention Tips

  • Seal cracks, gaps, and open doors to block entry points.
  • Remove leaf litter and debris from the perimeter of your home.
  • Schedule a spring pest control treatment to eliminate early infestations before they grow.

Summer

June – August

During Minnesota’s warmer months, pests are most active. Increased temperatures and outdoor activities mean more opportunities for pests to bite, sting, and spread diseases.

Active Pests in West Central Minnesota

  • Mosquitoes
  • Wasps and bees
  • Flies
  • Ticks
  • Ants
  • Cockroaches
  • Spiders
  • Mice

Why These Pests Emerge

Warm temperatures and plentiful food sources draw pests in large numbers.

Wasps build nests around eaves, decks, and trash bins. Mosquitoes breed in standing water, while flies and cockroaches thrive where food and moisture are readily available.

Braness Prevention Tips

  • Keep trash bins sealed tightly.
  • Eliminate standing water around your yard and trees.
  • Use safe, pet-friendly pesticides for tick and flea prevention.
  • Schedule a summer pest control treatment with Braness to protect your home and family.

Fall

September – November

As temperatures cool and early fall sets in, pests seek warmth indoors. This season brings a surge of nuisance pests and rodents looking for shelter before winter.

Active Pests in West Central Minnesota

  • Boxelder bugs
  • Asian lady beetles
  • Spiders
  • Beetles
  • Rodents (mice and squirrels)
  • Centipedes
  • Millipedes

Why These Pests Emerge

Boxelder bugs and Asian lady beetles cluster on sunny walls and slip inside homes through small openings. While mostly harmless, they can appear in large numbers and quickly become a nuisance.

Rodents invade attics and basements, chewing on wires and contaminating food.

Braness Prevention Tips

  • Seal cracks and repair window screens before temperatures drop.
  • Store food in sealed containers and keep counters clean.
  • Inspect attics and crawl spaces for rodent nests.
  • Schedule fall pest control treatments to stop invasions before they start.

Winter

December – February

During winter, pests don’t disappear — they simply move inside. Rodents, spiders, and cockroaches become the primary threats, posing health risks and causing damage to property.

Active Pests in West Central Minnesota

  • Rodents (mice and rats)
  • Spiders
  • Cockroaches
  • Bed bugs
  • Head lice

Why These Pests Emerge

As temperatures fall, pests search for warmth and food sources.

Mice can squeeze through openings as small as a dime, while cockroaches hide near appliances and plumbing where moisture is present.

Braness Prevention Tips

  • Keep food sealed and clean up crumbs immediately.
  • Set traps in attics, basements, and storage areas.
  • Seal gaps around doors, vents, and utility lines.
  • Schedule a winter pest control treatment to maintain a pest-free home.
