Homemade Insecticidal Soap Spray

Soap has been used for centuries as an all-purpose pesticide.It disrupts insects’ cell membranes, and kills pests bydehydration. The key is not to use too much soap, or you’llalso kill the vegetation near the pests. If you follow the proportion of soap to water in the Soap Spray recipe, below,the vegetation should be fine.

Doug Harp, a graphic designer friend, first alerted me tosoap as an effective all-purpose pesticide when he used Dr.Bronner’s Liquid Peppermint Pure-Castile Soap diluted withwater to kill the gypsy moths that had infested his appletrees. We were working on a project together, and I’d getfaxes updating me on his kill rate (this was back before e-mail!),which, much to his delight, was excellent.

Note: Buy a liquid soap and not a detergent. Health foodstores have liquid soaps, such as Dr. Bronner’s Pure-CastileSoaps.

 

Insecticidal Soap Spray
1 to 2 tablespoons liquid soap
1 quart water

Combine ingredients in a bucket, mix, then transfer to a spraybottle as needed.

 

All-Purpose Pesticide Soap Spray
Strong smelling roots and spices such as garlic, onions,horseradish, ginger, rhubarb leaves, cayenne and other hotpeppers, are all known to repel insects.

INGREDIENTS
A handful of roots and spices
Enough boiling water to cover
Soap Spray (recipe, above)

Add the roots and spices to the bottom of a mason jar. Coverwith the boiling water, screw on the top, and let set overnight.Strain, and add to the Soap Spray. Note that this will rot,so use it all up or freeze leftovers for another time.

 

Variation: Garlic Spray
Use 1 to 2 heads garlic. Deer and rabbits hate the smell
of garlic.

Truly no need to buy the rather expensive commercial insecticidal soap. Besides, Dr Bronner's smells a lot better than Safer's!

@cora you're right you can get insecticidal soaps in a variety of stores now. Safer Brand has one in particular that is organic which I personally recommend: http://www.saferbrand.com/store/garden-care/5118
