Overwintering Insects

When the temperatures drop, insects need to seek shelter and warmth.  Insects are not endothermic like animals; they cannot create their own heat internally. They are ectothermic, which means they need to rely on other sources to keep them warm.  The various ways insects handle the cold is known as overwintering.

Some insects, like the Monarch butterfly, migrate.  Other insects, like caterpillars bury their eggs and their growth is suspended, a process known as diapause, until warmer weather arrives. Dragonfly and cricket larvae will actually live underneath ice in ponds.

Ladybugs, stinkbugs and wasps like to hibernate in warm buildings. Stinkbugs like curtains and windowsills; wasps prefer attics and eaves in homes.  They typically stay in their chosen warm spots until the temperatures start to rise.  However, if there is a warm day in February or March, they will appear, under the assumption that spring is here.

You can control indoor emergence of overwintering insects by preventing them from entering your home or office. Ideally you should inspect your home before it gets cold.  Ways to prevent insects from seeking shelter include:

  • Seal openings near windows and doors.
  • Make sure vents, outlets and pipes do not have openings, even small ones, around them where insects could come in.
  • Inspect all window screens and repair any that are damaged.
  • Inspect siding and foundation and seal any openings.

Now that winter is here, insects may already be inside, however, it is still a good time to schedule an inspection for treatment and to prevent any more insects from joining them.  Call 800-457-3785 to schedule an appointment today.
