How to Make and Use Homemade Insecticidal Soap

Making homemade insecticidal soap is a simple and effective way to control pests on your plants. This solution is made from a combination of mild dish soap and water, which breaks down the exoskeletons of insects and dehydrates them.

To make homemade insecticidal soap, you'll need to mix 1 tablespoon of mild dish soap with 1 quart of water. This ratio is crucial for creating a solution that's potent enough to kill insects but gentle enough not to harm your plants.

Using this solution is as easy as spraying it directly on the affected areas of your plants. Make sure to spray the undersides of leaves and stems, as well as the soil around the base of the plant, to catch any insects that may be hiding there.

Making insecticidal soap is a straightforward process that requires just a few simple ingredients. To start, you'll need liquid dish soap, specifically one that doesn't contain additives like fragrance or moisturizer.

Liquid castile soap is a good option. For a small batch, choose a clean spray bottle or sprayer, and make sure it's completely cleaned and rinsed well if you're recycling one.

Mix 1 tablespoon of soap per quart of water, or 4 to 5 tablespoons of soap per gallon of water. This is a good starting point for most plants.

You can also use a more traditional recipe that makes an eco-friendly insect spray. This recipe calls for 2.5 tablespoons of vegetable oil, 2.5 tablespoons of pure liquid soap, and 1 gallon of warm water.

To use either recipe, dilute the mixture with water prior to application. For example, combine 1 teaspoon of the soap mixture with 1 cup of water before spraying it on plants.

Here are some guidelines to keep in mind when making and using insecticidal soap:

For best results, evenly coat the infested plants from top to bottom, making sure the spray comes into contact with the insects.

To use insecticidal soap, you'll want to evenly spray the mixture on all surfaces that are infested with pests or harmful insects. Be sure to hit the tops and bottom of affected leaves, as well as the supporting stems.

You should use insecticidal soap as often as you see heavy infestations, which could occur every two to three weeks. This is because small pests have short life cycles and can lay hundreds of eggs every other week.

Insecticidal soap works by penetrating insects' cuticles, causing cell collapse and desiccation, and resulting in dehydration and death.

The solution works on contact but should be reapplied roughly every three to six days, depending on the infestation level.

Insecticidal soap is effective against soft-bodied insects like aphids, cotton scale, thrips, mealybugs, white flies, and more.

It will not kill pests in their egg stage or hard-shell insects, so be sure to use it when the pests are present.

Insecticidal soaps are generally safe for humans and animals, but some people can get a rash from them, so it's best to wear gloves when applying.

Be aware that effectiveness may be limited if the soap solution dries or washes away, so make sure to thoroughly wet the insects.

Phytotoxicity may occur if applied during hot days, so avoid spraying if temperatures are over 90 F (32 C).

Insecticidal soaps have no residual activity left behind, so they rely on contact to kill pests, meaning if an insect hasn't come into contact with the spray, it isn't affected.

They also have no efficacy on insect eggs, so if you're trying to get rid of a pest like the azalea lace bug, you'll need to reapply the soap to its eggs.

All stages of the lace bug live on the underside of the leaf, which is often not thoroughly sprayed with insecticidal soap, so be sure to spray both the top and bottom of affected leaves.

Insecticidal soap works by penetrating an insect's cuticle, causing cell collapse and desiccation, which results in dehydration and death.

The solution is applied on contact and should be reapplied every three to six days, depending on the infestation level.

Insecticidal soap contains fatty acids that remove a protective layer from the outside of the insect, damaging the interior cells and causing a quick death.

This type of soap is effective against soft-bodied insects, including aphids, cotton scale, thrips, mealybugs, and white flies.

Soft-bodied insects are the target of insecticidal soap because it dissolves their exoskeleton, causing them to dehydrate.

Insecticidal soap is not a preventative treatment and should only be used when these insects are present.

You should use it as often as you see heavy infestations, which could occur every two to three weeks, due to the short life cycles of these pests.

The soap is applied by evenly spraying the mixture on all surfaces infested with pests, making sure to hit the tops and bottom of affected leaves, as well as the supporting stems.

It's best to avoid using insecticidal soap for just one or two bugs, as those can be picked off by hand.

You don't need to rinse your plant immediately after applying insecticidal soap, but repeated use can lead to a build-up of residue on the leaves.

After many applications, it's a good idea to spray the leaves with water to remove any residual build-up.

To prepare and apply insecticidal soap, you'll need a few simple materials on hand.

A spray bottle is a must-have for mixing and applying the soap solution.

Distilled water is also necessary, as it helps to dilute the soap and make it safe for use on plants.
