Does Neem Oil Kill Spiders?
Neem oil is a natural pesticide that is effective against many types of bugs, including spider mites, aphids, and whiteflies. However, when it comes to spiders, neem oil may not be the most effective solution.
While neem oil can smother and kill spider mites, it may not have the same effect on spiders. Spiders have a waxy coating on their bodies that can make it difficult for neem oil to penetrate and suffocate them.
That being said, neem oil can still be used as a spider repellent. The strong scent of neem oil can deter spiders from entering your home or garden. Additionally, neem oil can be used to treat other pests that spiders may feed on, such as aphids or whiteflies, which can indirectly reduce the spider population in your area.
What Is Neem Oil And How Does It Work As A Pest Repellent?
Neem oil is a natural product extracted from the seeds of the neem tree. It has been used for centuries as a pesticide and is known for its effectiveness against a wide range of pests. The active ingredient in neem oil, called azadirachtin, works by interfering with pests’ reproductive cycles, preventing them from feeding, acting as a repellent, and even acting as a contact insecticide that kills them instantly.
Neem oil works by suppressing hormones that bugs have the urge to feed on leaves, which leads to starvation. Since neem oil is a thick substance, it works to coat bugs, suffocating them. This instant remedy works on the bug depending on the stage of life the bug is in; typically, the smaller and more susceptible it is to suffocation on contact. Types of minor bugs that will die on contact include aphids, mites, and whiteflies. Neem oil not only prevents bugs but it also acts as a fungus repeller. It works to prevent mildew, rust, leaf spot, and black spot on your plant’s leaves.
When it comes to spiders, neem oil may not be effective in killing them directly due to their waxy coating. However, neem oil can still be used as a spider repellent due to its strong scent. Additionally, using neem oil to treat other pests that spiders may feed on can indirectly reduce the spider population in your area.
It is important to note that neem oil should be applied in the morning or evening when beneficial bugs are dormant and not feeding or pollinating. Avoid using the spray in the middle of the day when the sun and heat could burn the sprayed foliage. Neem oil is safe for the environment and can be used throughout the planting season as it affects insects during all phases of their development.
How To Use Neem Oil For Spider Control
If you decide to use neem oil to repel spiders or indirectly control their population, here are some tips for effective application:
1. Dilute the neem oil: Neem oil is highly concentrated and should be diluted before use. Mix 2 ounces of neem oil with 1 gallon of water and add a few drops of liquid dish soap to help the oil mix better with the water.
2. Apply in the late afternoon or evening: Apply the neem oil spray in the late afternoon or evening hours so that it can dry overnight and not damage the plant once temperatures increase the following day.
3. Use a mist or cone setting on your sprayer: Set your sprayer nozzle to a mist or cone setting to cover the plant’s foliage as completely and evenly as possible. Spray both the tops and bottoms of all leaves, as spider mites are notorious for clinging to the undersides of foliage and in the folds of curled leaves.
4. Schedule regular applications: You will not be able to achieve 100% coverage across all affected plants in a single day. Schedule regular, thorough applications of your neem oil spray so that you’ll catch any spider mites that managed to avoid earlier sprays.
5. Test on a small area first: Different plants may have different sensitivities to neem oil, so be sure to test this on a small area first before applying it to the entire plant.
Is Neem Oil Safe For Beneficial Insects?
Neem oil is considered safe for many beneficial insects, including ladybugs and predatory mites. These insects are not affected by neem oil and can continue to thrive in your garden even after neem oil is applied. Honey bees and other pollinators like butterflies are also generally safe from neem oil as long as they are not sprayed directly.
However, research suggests that neem oil can have negative effects on green lacewings, reducing hatchability while increasing mortality rates. It’s important to note that green lacewings are beneficial predators that prey on invasive pests, so it’s important to consider the potential impact of neem oil on these insects before using it in your garden.
Parasitoid wasps are another beneficial predator that may be impacted by neem oil. While neem oil is generally safe for parasitoid wasps, it’s important to avoid spraying it directly on these insects to prevent any potential harm.
Other Natural Spider Repellents To Try
If you’re looking for other natural spider repellents to try, there are several options available. One effective method is to use a mixture of water and liquid dish soap. The dish soap disturbs the egg cycle of spiders, while citrus-scented soaps like lemon, lime or orange can also repel them.
Another option is to use essential oils, such as peppermint, cinnamon, tea tree, lavender, rose, eucalyptus, or cedar. You can add 20 drops of any of these oils to water in a spray bottle and spritz it around the house where you see spiders. Planting mint around the exterior of your home, especially under windows, can also be effective in deterring spiders. Additionally, placing cedar chips, blocks or balls in areas where spiders congregate can help keep them away.
Garlic is another natural spider repellent that you can try. Crush a few garlic cloves and drop them into a spray bottle with water. Let it sit for a day and then spray it in corners and along the baseboards where spiders are often found. Vinegar can also be mixed with equal parts of water in a spray bottle and sprayed where spiders are spotted.
Lastly, you can try using chrysanthemums as a border planting around your home to keep spiders away. These flowers contain naturally-occurring pyrethrin, an insecticide that repels ticks, spider mites, Japanese beetles and other garden pests. You can also make a DIY pest spray using chrysanthemums to keep bugs at bay.
