Cold Weather Doesn’t Stop Pest Activity in the Fort Leonard Wood Area
Many homeowners in Waynesville and St. Robert believe that winter forces pests to die off. However, Missouri’s climate doesn’t eliminate bugs — it simply changes how they survive. Cold weather often drives insects and rodents closer to homes as they search for warmth, moisture, and shelter.
Plank Termite & Pest Control receives a surge of winter pest calls every year from this region. Below are the most common myths we hear — and the truth behind them.
Myth #1: Bugs Die When It Freezes
Reality:
Very few insects actually die during winter. Most pests have natural survival methods that allow them to push through even the coldest days.
Common overwintering strategies include:
- Entering diapause, a cold-weather survival pause
- Hiding inside wall voids, crawlspaces, basements, and attics
- Staying active inside heated homes
- Surviving as eggs or larvae until spring warmth arrives
Common winter survivors in Waynesville & St. Robert include:
Myth #2: Spiders Are Not Active in Winter
Reality:
Spiders stay active indoors throughout winter, especially brown recluses. With heated homes and military housing, spiders gravitate toward warm, undisturbed areas.
Common hiding places include:
- Basements and utility rooms
- Laundry rooms
- Closets and storage areas
- Behind furniture and boxes
In the Waynesville and St. Robert region, winter spider activity is common because pests they prey on remain active indoors.
Myth #3: Rodents Go Dormant During Winter
Reality:
Rodents do not hibernate. In fact, mice and rats become more active indoors during winter. As temperatures fall, rodents seek warmth and food inside garages, kitchens, crawlspaces, and attics.
Common rodent winter nesting spots include:
- Pantries and kitchen cabinets
- Insulation in attics
- Crawlspaces and basements
- Utility lines and HVAC chases
- Stored boxes and cluttered areas
Neighborhoods around Fort Leonard Wood see elevated rodent activity because of close housing, shared walls, and numerous entry points.
Myth #4: Mosquitoes Disappear Completely
Reality:
While adult mosquitoes die off in freezing temperatures, their eggs survive winter. These eggs lie dormant until spring when moisture and warmth allow them to hatch.
Mosquito eggs overwinter in:
- Damp soil
- Frozen containers
- Leaf piles and debris
- Clogged gutters
This is why mosquito season around the Roubidoux Creek and base-area neighborhoods often begins early.
Myth #5: Winter Pest Control Isn’t Necessary
Reality:
Winter is one of the most critical seasons for pest prevention. Pests hide deeper in cracks, rodents search for nesting sites, and overwintering insects move into warm wall voids.
Winter pest control services help:
- Reduce spring populations before they emerge
- Control spiders and roaches sheltering indoors
- Prevent rodent nesting and wiring damage
- Treat wall voids and utility penetrations
- Identify moisture and structural issues early
