RECIPE #61 Mosquito repel
Lemon scented dish soap and lemon scented ammonia used at equal
parts with water will be a good repellent for mosquitoes.
1 teaspoon each to 1 quart water
1 Tablespoon each to 1 gallon water or
1 cup each in a 20 gallon hose end sprayer.
Spray under leaves and in areas where mosquitoes hang out.
I got this off the web. It sounds simple enough. However, I was told not to mix ammonia with other chemicals. Does this formula sound safe enough for minimal human and pet contact?
