Natural DIY pest control
Homemade remedies are inexpensive and you know what is going into your garden. Many
homemade sprays have been successful in ridding gardens of unwanted pests. Here are a few
Mites and Aphids: Mix one tablespoon olive oil and a few drops of mild non-toxic dish soap into a quart of water. Place in a spray bottle and shake well. Spray plant from above down, and
from below up to get the underside of the leaves. The oil smothers the insects.
Grubs: Get milky spore granules and spread on the soil. This causes the grubs to contract a disease that kills them. This natural method only kills the grubs but doesn’t harm other beneficial bugs. One treatment lasts for up to 40 years!
Slugs and snails: Sprinkle diatomaceous earth over plants and along the edges of your garden.
The small earth particles are sharp and can destroy insects, slugs and snails outer shells.
Pests: Coffee has a strong odor which repels insects and animals. You can put grounds around
plants in a circle to repel ants, slugs and rodents. Small amounts of coffee grounds can be added directly to top soil. Coffee is high in minerals which is another reason to add to your gardening
arsenal. The one exception is that coffee isn’t a good mix with tomatoe plants.
Mosquitoes: Thai lemongrass is a great mosquito repellent. It contains the natural oil citronella.
You can buy Thai lemongrass plants or grow them yourself, and they are pretty hardy. To use one as a mosquito repellent, break the stalk and peel away the outer leaves to get to the pulp. Rub the pulp over exposed skin. You can also add it to a spray bottle with alcohol for spray applications.
Lemongrass plants around the patio will also help repel mosquitoes.
