For insects, residential mosquito spraying is like dropping a nuclear bomb — there's a lot of collateral damage to unintended targets. It's important that homeowners exhaust a variety of other tactics before picking up the phone to call a mosquito control company.

Here are some tips from the Georgia Board of Public Health suggests:

  • Eliminate sources of standing water (flower pots, buckets, etc.) where mosquitos breed 

  • Add mosquito larvicides (e.g., BTI “dunks”) to fountains, ornamental ponds, etc. These safe, biological products kill mosquito larvae before they become biting, breeding adults

  • Cut back overgrown vegetation that can harbor mosquitos

  • Keep rain gutters clear of wet leaves and standing water

  • Apply skin-based insect repellents to exposed skin when outside  (DEET is proven safe and the most effective repellent against mosquito bites; Picaridin and Oil of Lemon Eucalyptus are proven alternatives.)

  • Avoid outdoor activity at dawn and dusk when mosquitoes are most active

  • Use fans to circulate air when entertaining outside

  • Wear loose-fitting pants and long-sleeved shirts to reduce skin exposure

  • Fix damaged window screens to deny mosquitoes entry

Prevention Tips

Killing mosquitoes in the larval stage is far easier and safer than killing flying, biting, reproductive adults. In addition to eliminating sources of standing water, BTI dunks are a targeted larvicide that kills mosquitoes in the larval stage of development. It is a biological agent and is harmless to bees.

Pesticide Drift

Pesticide applicators are required to mitigate chemical drift. This means not spraying on windy days when chemicals can drift into non-target areas or neighboring properties.

Residents who observe unwanted pesticide drift occurring in their yards can file a complaint with the Georgia Department of Agriculture’s Pesticide Complaints and Enforcement office’s Nancy Hall:  (404)-656-9371 or  Her office will send someone to collect samples and, if evidence of drift is found, issue a warning to the operator.
