Even though they look threatening, most spiders pose little to no damage to humans and are beneficial in naturally controlling the insect population. But when a spider is at your own home hanging upside down over your head, you normally aren’t worried about the benefits they bring and just want them out. Luckily, you have several alternatives when it comes to homemade spider repellants which don’t include expensive and toxic chemicals but will help keep these creepy crawlies in the bay.
Vital Oils
Essential oils are a concentrated fluid derived from plants. These oils usually have the smell, flavor or “essence” of the plant it is obtained from. Several essential oils including cinnamon, peppermint, clove, lavender and citrus — can be diluted with water to produce a homemade spider repellant spray. A mixture of 5 drops of one or several essential oils and 1 gallon of water combined in a spray bottle helps maintain areas free of spiders. Spray corners, cracks and crevices where spider webs have a tendency to appear. Another choice is to dampen a cloth with the spray and wipe surfaces — such as cupboards — to keep spiders from the area. Regrettably, these sprays will dissipate over time and need reapplying to keep spiders out of your home.
Diatomaceous Earth
Diatomaceous earth is a powder made of algae fossils that contains microscopic sharp borders. These borders cut insect larvae and induce some insects — such as cockroaches and spiders — to dehydrate and die. The sharp edges of diatomaceous earth will not harm people, pets or kids, though inhaling the dust can lead to nose and throat irritation. Sprinkle diatomaceous earth around your home as a perimeter barrier to prevent spiders from penetrating. Diatomaceous earth may also be scattered in crawlspaces, around windows and doors, and in toilets, cracks and crevices or any other concealed area spiders frequent.
Plants for Repellant
Hedge apples (Maclura pomifera) — also known as Osage orange — grows at U.S. Department of Agriculture plant hardiness zones 4 through 9. This 35- to 60-foot tree creates sharp thorns and large fruit, which has been used for many years as a spider deterrent. But there is no scientific evidence to support these claims, according to Iowa State University, and even though insect-repelling chemicals are pulled from the hedge apple juice, there aren’t any scientific explanations as to why it might deter spiders.
Factors
The ideal method to managing these beneficial animals is to make your home less desirable for spiders. Controlling insects — such as silverfish — at your home will keep spiders from moving in. Keep the exterior of your home around windows and doors free from allergens. Regularly sweep cobwebs from the corners and ceilings of your home with a broom. An alternative is to use a yellow light bulb for outdoor lights. The yellowish light attracts more insects than white bulbs, reducing the spider’s food resource. Without food, spiders will depart the area.
