How to Make Garlic Mosquito Spray


You've tried all sorts of insect repellents. They're all expensive, some are toxic, and none work particularly well. Do you have some garlic and hot peppers in your kitchen? You can easily mix up a batch of bug spray using garlic as the active ingredient. The sulfurs in garlic serve as a natural insect repellent. This non-toxic brew will not only keep biting insects at bay, but has an aroma that will help whet the appetite of your BBQ guests.

Step 1

Finely chop the garlic and hot peppers.

Step 2

Pour the chopped ingredients into a mixing bowl. Add the dish soap.

Step 3

Stir with a mixing spoon. While mixing, crush the garlic and peppers with the edge or back of the spoon, releasing more of the juice into the dish soap.

Step 4

Fill the milk jug halfway with tap water. Pour in the mixed ingredients and seal the cap.

Step 5

Shake vigorously.

Step 6

Reopen the jug and fill the rest of the way with tap water. Seal the jug.

Step 7

Shake gently and store overnight in a cool, dark place.

Step 8

Mix your concentrate with water. Mix fresh tap water with your garlic concentrate in a spray bottle at a ratio of 64:1. If you intend to use the same spray bottle each time, mark a fill line at the bottom for the proper volume of concentrate for that bottle.

Step 9

Apply your insect repellent like other commercial repellents.
