Is there an omri product to spray for mosquitoes?
If mosquitoes are prevalent on a lawn, is there a safe product to use with a garden hose to spray the lawn? I was thinking that an omri product would be best. I am trying to advise a relative who has a new home. This person lives in Damascus Md.

Mosquitoes can be an area wide issue and there are many mosquito species in MD. Among them is the Asian tiger mosquito. They are small, black with white striping on the legs and are out flying (and biting) during the day. If the mosquitoes come out primarily at night, then it is most likely a native mosquito which breeds in bodies of water such as wetlands that is the problem. But no matter what the species is the control tactics are very similar.
Reducing populations involves eliminating any water that is present in containers and other areas on your property. For additional information see our mosquito page, http://extension.umd.edu/hgic/mosquitoes.
Any water you can't regularly drain or change should be treated with mosquito dunks which contain Bt, a biological insecticide. Mosquitoes like to rest on plants that tend to hold moisture on their leaves, so increase air circulation in an area by pruning shrubs and cutting down tall weeds.
We do not have recommendations for low toxic sprays and don't recommend spraying or fogging with an insecticide for multiple reasons. The main reason is that the recommended insecticides can kill non-target species, including many beneficial insects and pollinators. Sprays often miss the target and do nothing to control the larvae. It is more effective to target the larva than spray the adults. Plus multiple sprays are necessary which is time consuming and expensive.
Protect yourself from mosquito bites by wearing long sleeves, pants, and a hat (you can even find clothes treated with insecticides that repel insect pests). Repellents containing Deet work. Make sure to follow label instructions and consult with your pediatrician before applying to children. See our publication on preventing mosquito bites:
