Why Does Rain Increase Mosquitoes in Charlottesville, VA?

How Rain Affects Mosquito Activity in Charlottesville, VA

If you’re wondering why mosquitoes seem to increase after a nice Charlottesville rainfall, you’re not alone. Like clockwork, the buzzing, biting, and mosquito activity all seem to increase and intensify after a rain or thunderstorm. The reason? Because there are more areas to breed and reproduce.

Mosquitoes only need one bottle cap’s worth of water to breed. That may sound shocking, not only because of the minuscule size, but what that means for simple puddles and bird baths. After rainfall, you can expect the mosquito population to increase within 7-10 days after. With this quick hatching cycle, a once manageable mosquito problem can quickly grow out of hand.

With the Rivanna River, local creeks, and Blue Ridge runoff, these mosquito breeding havens create larger pools and settled water for mosquitoes to lay their eggs in. It may seem as though there’s nothing you can do to avoid this reality, but Mosquito Squad of Charlottesville can help.

Charlottesville, VA Mosquito Control Treatment FAQs

You may be wondering how rainfall affects the potency of our Charlottesville mosquito control barrier treatment.

Although rain creates standing water, humid afternoons, and damp environments, it does not wash away mosquito treatments that have been properly applied. Our EPA-registered blend binds to foliage and surfaces, in order to create a barrier between mosquitoes and the areas where they prefer to inhabit. For particularly heavy periods of rainfall, re-application may need to be done sooner, and it will be essential to dump any standing water that you may have immediate access to. Here are a few simple ways that the 7 T’s of Mosquito Control can help after heavy rainfall.

As with many things in life, mosquito control results take time. Mosquitoes will continue to linger shortly after your first barrier treatment, but an 85-95% reduction will occur within 48 hours from the initial application. Additionally, we will continue to treat your Charlottesville home on a three-week basis to ensure that the mosquito population is properly addressed and deterred throughout the spring, summer, and fall seasons.
