Often sprinkled around the house in powder form, boric acid is a dessicant best known for how well it works in combatting cockroaches. But no matter what insect or spider you're trying to battle in your home, boric acid works by attacking and damaging the exterior shells of pests like roaches and ants on contact, which ultimately leads to death by dehydration. The powder, which is super low in toxicity and not damaging to humans or pets, can also be ingested by insects, at which point it attacks their nervous systems. But to be successful with boric acid, it's important to make sure that you're using it in dry places to see the best results.
Created using the fossil remains of diatoms, which are a group of algae, diatomaceous earth is a naturally occurring sedimentary deposit that can be extremely powerful in ridding your home of pests thanks to its abrasiveness. The powder essentially works by fatally damaging the outer shell of an insect upon contact, causing the insects' body to release necessary moisture and leading to death within a few days, or in some cases, hours. Like boric acid, though, diatomaceous earth, which is also pretty harmless to people and pets, should be kept dry for best results against pests.
Used as a solution for everything from car sickness to sleep troubles, essential oils can also play a strong role in eliminating pest problems in your home naturally and gently. Of course, with a huge variety of oils to choose from, you'll have to select your mixture based on the pest you're combatting. While oils like peppermint, garlic, and citronella might work against an ant infestation, for example, you're better off using varieties like cedarwood, spearmint, and orange againt aphids. Once you have a good idea of the best oils for your pest problem, create a powerful spray to battle your bugs by diluting your potent oil mixture with a bit of water.
Organic Bug Spray
If your first instinct when it comes to fighting insects is always to reach for a spray, you can steer clear of toxic bug killers and repellants by opting for an all-natural option that is relatively lower in chemicals than common commercial products. If you find pests to be a major problem in your garden, try something like earth-friendly garden pest killer and repellent Hot Pepper Wax. If you're looking to keep pests like cockroaches, flies, and spiders out of your home, try Bugs 'R' Done, a botanically-derived insecticide made with orange peel oil. Another option is to create your own natural pest repellent spray using commong ingredients from your pantry, like garlic and pepper, that is strong on pests, but gentle on you and your home.
