Dealing with spider mites can be frustrating, but it’s important to get rid of them if you want to keep your plants healthy. If left unchecked, they can cause serious damage to both indoor and outdoor plants.
Spider mites are tiny little pests that can infest beans, curcubits, tomato plants, and other vegetables and plants [1]. They suck juice from plant cells, which can seriously damage the plant.
Here’s how to get rid of spider mites naturally:
1. Remove Infested Leaves
To tackle the problem effectively, heavily infested leaves need to be removed and disposed of properly.
Just place them in a plastic bag, seal it up tight, and dispose of it. However, if the whole plant is infested, you’ll need to get rid of it entirely.
Taking these measures will help prevent other plants from becoming infected with spider mites.
2. Hose Them
This is one of the cheapest and quickest ways to deal with these plant pests. Using a garden hose to spray water on your plants should flush away webspinning mites.
If the pressure is strong enough, this will wash them away entirely. But be careful not to damage your plants in the process.
3. Soap and Water
Another effective home remedy to kill spider mites is to put a little dish soap in some water and spray it on them.
Just combine three tablespoons of liquid dish soap with a gallon of water. Shake well and use it to mist your plants. The soapy water solution will suffocate the critters.
Alternatively, purchase an insecticidal soap such as this one. It works great to get rid of the two-spotted spider mite.
4. Rosemary Oil
Rosemary oil works great as a natural repellent for spider mites [2].
Make a homemade spider mite spray by mixing three teaspoons of rosemary oil and a teaspoon of organic liquid soap with a liter of water.
Shake well and spray indoor, outdoor, and greenhouse plants.
5. Lemon Juice
This is another easy DIY remedy you can try. To make your own natural spray for spider mites, mix together some water and fresh lemon juice in a 2:1 ratio.
Finally, fill up a spray bottle and douse all the affected plants. This solution is safe to use on your plants and will help keep these pests at bay.
6. Natural Predators
Beneficial insects like ladybugs, minute pirate bugs, and lacewings will prey on spider mites. Predatory mites are also helpful in this way.
7. Neem Oil
Neem oil is a popular pest repellent that works great against mite pests. Therefore, use it to make a DIY spray to help control spider mites.
For the recipe, combine two tablespoons of neem oil, one teaspoon of liquid soap, and a gallon of water. Shake well and spray your plants.
8. Diatomaceous Earth (DE)
Food-grade DE is a great home remedy for killing spider mites on houseplants. It also works great at controlling many other garden pests.
Diatomaceous earth causes a dehydrating effect that will kill these pests if they come into contact with it. It is very effective in the larval and adult stages.
Dust the powder on the plant’s leaves, stems, and surrounding soil.
You can also make a homemade spider mite killer spray by mixing 4 tablespoons of diatomaceous earth with a gallon of water.
Use it to spray the critters. Once the solution dries out, it will dehydrate them to death.
9. Hot Pepper Spray
Hot pepper sprays are also great at controlling spider mites and other garden pests. Use jalapenos, chili, or cayenne pepper.
For a basic recipe, combine one teaspoon of hot pepper powder, a few drops of liquid soap, and a quart of water.
Shake well, and then let it sit overnight. Afterward, use the solution to spray both sides of the leaves.
10. Debug ON
This is a powerful organic pest control product. It contains an ingredient that has been shown to control many plant pests, including spider mites.
Debug ON acts as a repellent by keeping certain pests away from your plants. It also works as an insecticide that will kill many insect pests.
11. Organocide
Organocide is another organic product that you can use to kill spider mites on plants. It is great for use in the vegetable garden.
It also acts as a fungicide, suppressing plant diseases such as powdery mildew and downy mildew. But it is not advisable that you use it on indoor plants.
12. Garlic Spray
The garlic water solution is another impressive home remedy for spider mite control.
Blend five cloves of garlic in two cups of water. You can also add to the solution a little liquid dish soap.
Blend until smooth, and then strain. Use this homemade spray immediately on the affected plants.
13. Bonide Mite-X
This is a botanical pesticide containing azadirachtin. Apart from working against mites, Bonide Mite-X also kills aphids and thrips.
Moreover, you can use it on both indoor and outdoor plants. This includes shrubs, fruit trees, flowers, and greenhouse plants.
