What’s the best time to KILL mosquitoes, when they’re in the water phase? Any other time you are swatting them and they’re out for blood. Mosquitoes can be tricky, some are known to be in your area and others may fly in from over a mile away. I have seen mosquitoes in tires and in beer bottles with only 1/2 inch of water present. We all know what an absolute nuisance they can be.
There are some innovative products available including this one from www.in2care.org and I also recommend Flyweb for inside the house.
