As the old saying goes, April showers bring May flowers, but they also bring… pests. Rain can bring in a flood of unwanted pests to your home. Some of the most common rainy day pests include mosquitoes, ants, roaches, and centipedes to name a few. Heavy rains will often destroy the shelters of these pests, bringing them indoors in search of a replacement shelter and nearby food source. Here’s a look at some of the most common pests that emerge after heavy rains and some ways to prevent them.

Mosquitoes

Mosquitoes
Mosquitoes thrive in warm, humid environments so post rainfall areas are ideal for them. Mosquitoes also lay their eggs in standing water which often accumulates after a heavy rain. One pro to heavy spring rains is that they can actually destroy any existing mosquito eggs before they hatch helping to reduce the mosquito population in an area.

Ants

Ants
Ants usually build their colonies in the topsoil near available food sources. These areas are at high risk for flooding when it rains. When their colonies flood ants have 2 choices – get swept away in the water or seek out dry, higher ground which is usually in our homes. Once indoors, ants resume their regular activity of looking for food. They are usually found around kitchen sinks, pantries, cupboards, and window sills.

Roaches

Roaches
Roaches tend to live in places that are easily prone to floods. When the cold weather of  winter sets in, roaches will seek out shelter in warm humid places like drains, pipes, foundations, crawlspaces, and sewers. When the spring rains flood these spaces the roaches are forced out. They avoid drowning by making their way into your home. Roaches need humidity to thrive and rainfall creates all sorts of inviting places for them to live.

Centipedes

Centipedes
Centipedes are attracted to humid environments so rainfall creates lots of ideal environments for them to thrive in. Centipedes are also hunters and will follow their prey (roaches, ants, sowbugs) into your home when they try to get in out of the rain. Centipedes are usually found in bathrooms, attics, basements, and garages. If you have centipedes in your home they are usually a good indication that you have another pest problem, as well.

Prevention

The key to controlling rainy day pests is to try and prevent them from getting inside in the first place. Here are some tips for controlling these pests:

  • Get rid of any standing water that accumulates with rainfall.
  • Invest in scheduled pest control services (mosquito control, routine preventative pest control, etc)
  • Keep shrubs and trees trimmed back from your home to eliminate easy access for pests.
  • Clean gutters regularly, especially after a heavy rain.
  • Seal any entry points such as window screens, cracks, and crevices with caulk.
  • Remove trash and debris from your home.
  • Clean up crumbs and spills immediately.
  • Keep sink and tub drains clear.
  • Declutter your home and garage.

As always, if you suspect you have a pest problem contact a licensed pest control company who can help properly identify the type and source of the pest problem and provide you with the most up-to-date treatment plan for your situation.
