7 Weird and Wacky Natural Remedies for Houseplant Pests
As a passionate houseplant enthusiast, the last thing you want is for your beloved greenery to become infested with pests. But sometimes, despite your best efforts, pests can still find their way into your home and onto your plants.
When this happens, it can be tempting to turn to harsh chemicals and pesticides to get rid of the pests. However, these products can be toxic to both your plants and the environment. Fortunately, there are plenty of natural remedies out there that can effectively control and eliminate houseplant pests without the use of chemicals.
Here are seven weird and wacky natural remedies for houseplant pests that you may not have heard of:
1. Diatomaceous earth
Diatomaceous earth is a fine powder made from the fossilized remains of diatoms, a type of hard-shelled algae. It works by cutting through the exoskeletons of insects, causing them to dehydrate and die. To use diatomaceous earth as a natural pest control, simply sprinkle it around the base of your plants or directly on the pests themselves.
A study found that using diatomaceous earth was effective at controlling several types of houseplant pests, including aphids, whiteflies, and mealybugs. The researchers also noted that diatomaceous earth had a low toxicity to humans and other mammals, making it a safe and natural alternative to chemical pesticides.
2. Neem oil
Neem oil is a natural pesticide extracted from the seeds of the neem tree (Azadirachta indica). It works by disrupting the hormones and reproductive system of pests, preventing them from reproducing and eventually leading to their death. It is particularly effective against aphids, whiteflies, and mealybugs.
To use neem oil as a natural pest control, mix it with water and a mild soap and spray it directly onto the affected plants. Make sure to follow the instructions on the label, as using too much neem oil can harm your plants.
3. Garlic spray
Garlic is not only a delicious addition to your meals, but it can also be used as a natural pest repellent. To make a garlic spray, blend several cloves of garlic with water and a mild soap, then strain the mixture and transfer it to a spray bottle. Spray the mixture directly onto the pests or around the base of your plants to keep them away.
One case study found that using a garlic spray was effective at controlling aphids on tomato plants. The researchers also noted that the garlic spray had a low toxicity to beneficial insects, making it a safe and natural alternative to chemical pesticides.
4. Cayenne pepper spray
Cayenne pepper is not only a spice, but it can also be used as a natural pest deterrent. To make a cayenne pepper spray, mix a few teaspoons of cayenne pepper with water and a mild soap, then transfer the mixture to a spray bottle. Spray the mixture directly onto the pests or around the base of your plants to keep them away.
One study found that using a cayenne pepper spray was effective at controlling aphids on tomato plants.
5. Beer trap
Believe it or not, beer can be used as a natural pest control method. Slugs and snails are attracted to the smell of beer and will crawl into the trap to get a taste. To make a beer trap, simply bury a shallow container, such as a jar or Tupperware, near the affected plants and fill it with beer. The slugs and snails will crawl into the trap and become trapped, unable to escape.
A case study found that using a beer trap was effective at controlling slugs and snails in a home garden. The researchers also noted that the beer trap was a safe and natural alternative to chemical pesticides, as it only targeted specific pests and had no adverse effects on other insects or animals.
6. Soap and water spray
A simple soap and water spray can be an effective natural pest control method for certain types of insects, such as aphids and spider mites. To make a soap and water spray, mix a few drops of mild dish soap with water in a spray bottle. Spray the mixture directly onto the pests or around the base of your plants.
7. Companion planting
Companion planting is a gardening technique in which certain plants are grown near each other to benefit each other in some way. Some plants can act as natural pest repellents when planted near susceptible plants. For example, marigolds and basil are known to repel certain types of insects, such as aphids and mosquitoes.
