Mosquitoes and West Nile Virus in Buffalo: What To Know

Pest Guides: Mosquitoes and West Nile Virus in Buffalo: What To Know

Mosquitoes are a nuisance in Buffalo summers, and some carry viruses. Here is how they breed in ordinary yards, what the state health department says about mosquito borne illness and how to reduce them.

How mosquitoes breed in a normal yard

Mosquitoes need only a small amount of standing water for their larvae. Clogged gutters, buckets, tires, plant saucers, tarps, birdbaths and low spots in the lawn can all breed them, which is why a clean looking yard can still have a mosquito problem.

What the state tracks

The New York State Department of Health monitors mosquito borne illness every season, including West Nile virus and eastern equine encephalitis. Most people infected with West Nile virus have no symptoms, some develop fever and aches, and a small number become seriously ill. The risk is higher for older adults and people with weak immune systems.

When mosquitoes are active in Buffalo

Activity starts in late spring, builds through summer after warm and wet weather and continues until hard frosts in fall. Dusk and dawn are the most common biting times.

What reduces mosquitoes at home

Empty standing water every week, clean gutters, keep screens in good repair, trim shrubs and tall grass and use an EPA registered repellent when outdoors. Professional mosquito control adds treatment of the shaded vegetation where adults rest, timed to the season.

What treatment can and cannot do

No treatment removes every mosquito because they fly in from nearby properties. A seasonal program plus removing standing water lowers the number that reach your patio considerably. Call 716-347-5858 to schedule a yard inspection.

Our mosquito control service handles exactly this: it starts with a professional inspection.
