How to Make Homemade Garden-Pest Spray

Repel garden pests, but keep plants' friends

Even the best-planned, healthiest garden will attract pests. Bugs, slugs and other creepy-crawlies like a tasty lettuce leaf or tomato just as much as humans do. But if you are gardening to provide food for your table, you won’t want to use toxic chemicals to deter invaders. There are lots of nontoxic and organic alternatives that are safe for use around people, pets and such beneficial critters as birds, toads, lizards, and even beneficial insects such as ladybird beetles, mantises and certain wasps that prey on the bad guys.

Common remedies used by organic gardeners include insecticidal soaps, oil sprays, sticky traps, pheromone traps, sprays using specific types of the bacterium bacillus thuringiensis, and physical barriers such as row covers. Using readily available ingredients, you can concoct a homemade garden-pest spray that can be used to prevent or treat insect infestations. Organic Gardening magazine developed this recipe:

Healthy soil ensures strong plants that are better able to fend off pests and diseases such as mildew, mold and leaf spot. And if all else fails, don’t hesitate to remove a stricken or infested plant from the garden. Just don’t put it in a compost bin — bag it for removal in the regular trash pick-up or, if local codes allow, burn it.

Planting the varieties most suited for your area also helps keep pests to a minimum.

Again, consulting the experts and doing some research will help you keep a garden that’s as pest-free and bountiful as possible.
