Warmer weather means many of us will be spending more time in our backyards. But that also means the potential to be bitten by ticks and an increase in the potential to contract Lyme disease. One way to combat this is to look for natural powdered insecticides that have the chemical pyrethrum. This natural insecticide comes from the chrysanthemum flower, and it has natural paralyzing properties for both ticks and fleas. The powder can be safely sprayed onto lawns and other surfaces to give you effective and eco-friendly tick control.
