How Rain Affects Insect Activity

Changes in temperature and the shifting seasons have a clear effect on the active pests in and around your home. There are other factors that occur mid-season though, and pests will react not only to changes in heat or daylight, but insects in the rain will behave a bit differently.

Insects are cold-blooded, so when the weather gets colder they can become more sluggish. Because they cannot produce their own body heat, insects will adapt by migrating to warmer weather or seeking shelter. They may hibernate by burying themselves underground, or they might make their way into your home to find warmth.

Warmer weather usually means that insects will reproduce. Increased temperatures also mean increased activity, which increases metabolic rates. Insects will then look for food, food they might find in your garden and in your kitchen.

Behavior changes when dry weather becomes wet weather. Pests that love moisture, such as mosquitoes, cockroaches, stink bugs, and termites, will increase their activity with the increase of moisture. After steady rains, those mosquitoes will search for standing water to lay their eggs, hoping to increase their population.

For those insects that do not care too much for the rain, they will instead try to avoid the moisture and look for a dry place elsewhere. That means that excessive rains can drive spiders, ants or roaches into your home. Some rainy conditions can even drive some pests out of their nests in the ground. When that happens, they can quickly make their way inside your house looking for food and shelter.

Conversely, dry weather can influence those same pests. If rains drove insects inside in search of warmth, a drought could send those insects inside in search of water. Other insects multiply and thrive in the dry weather, such as grasshoppers. 

It is difficult to predict the weather, and you may try harder than necessary to find a couple of dry days to call for a pest control treatment. You might fear that if it rains, that your treatment, and your money, has gone to waste. Fortunately, that is not the case.
