Will Sulfur Keep Flies Away?

Sulfur is a natural insecticide and is used in hundreds of commercial insecticides. It works by killing insects by interrupting their energy function. It can also be used as a fertilizer. It is a fungicide, too, which helps to keep bugs at bay.

It is important to follow application instructions carefully, because sulfur can cause irritation to skin, eyes, and throat. Wear protective gloves and goggles when mixing and spraying sulfur. Use caution when spraying sulfur because it may dry on plants and cause allergic reactions. Also, use caution in hot and humid climates, as sulfur may cling to the leaves of plants.

Another natural insect repellent is garlic. If sliced or crushed, garlic releases sulfurous compounds that repel insects. Garlic, in particular, is a good choice for keeping flies away because of its sulfur-based smell. You should eat at least a few cloves a day, preferably several days before you plan on going outside.

Sulfur can benefit both plants and livestock. It can make the protein in milk more digestible, and it improves reproduction. It also reduces stress and external parasites. Sulfur-based livestock feed is one way to use it.
