The struggle is real on a rainy day. It’s hard to roll out of bed, to trudge through the puddles, and to generally find motivation. But remember, it could be worse: for pests, a rainy day is a matter of life or death. While water is necessary for most pests’ survival, rain can also flood their homes, send their food sources into hiding, and force them to find shelter—like your house. Here are some of the New England pests you’re likely to see during and after the rain.
Ticks. When ticks get lots of moisture or humidity, their populations thrive. Ticks find food by “questing”, or climbing vegetation and latching on to a passing host- and in order to do that, they need enough humidity to absorb sufficient water from the air.
Mosquitoes. Mosquitoes only need a thimbleful of water in which to breed. Rainwater left standing in gutters, bird baths, pools, gardening equipment, pet bowls, and other receptacles, is perfect for a female mosquito to lay her (up to 300) eggs. Larva only need half an inch of water to survive, so even a little rain can increase mosquito activity in your yard.
Termites. Termites often swarm after a warm rainfall. The damp soil cues reproductive termites to pair off and begin a new colony. Rain also contributes to water damage and damp wood in and around homes, providing an appealing food source.
Ants. Many ant species build their colonies in the ground, meaning even a little rain poses a big threat of flooding. Ants must move to higher, drier areas, and your home can be an appealing option. Inside your home, they’ll have shelter and food—both of which can make ants so comfortable they might be hesitant to leave once the skies clear.
Centipedes. Centipedes are attracted to dark, humid environments with an available food source. Centipedes are predators that will essentially eat anything smaller than they are—like other pests that might be taking shelter inside your home.
