This concoction was relayed to me by a cousin. She knows that I am pestered by mosquitoes since we were young, that I am a magnet for mosquitoes. Anyway, this homemade concoction can be sprayed anywhere and there’s no risk with the pets. That’s the main concern, we have dogs inside The House that’s why we cannot use the aerosol insecticide. We can only spray when we are going on a road trip with the dogs. Here is the simple recipe – equal parts of olive oil, vinegar, shampoo. Any kind of oil will also do, any kind of vinegar and any kind of shampoo. Mix it and put in a sprayer. I have tried this before posting and the result is very encouraging.
