How Does Killing Aphids with Soapy Water Works?
Soaps work by interrupting the cell membranes of aphids. As the protective exterior—wax— is damaged, cell content leaks out, and the insect becomes dehydrated and dies.
Killing aphids with soapy water also works through a smothering or suffocating process. The exoskeleton of the aphid becomes covered in soap that it’s smothered to death.
Although it’s not fully understood as to how soap works to kill aphids (and other soft-bodied insects), it has been used for over 200 years.
This gives rise to an important question. Is killing aphids with soapy water effective? Let’s jump into it.
Is Killing Aphids with Soapy Water Effective?
How do you define “effective”? For any product to be “effective” it has to succeed in carrying out the task for which it is used. Does soapy water kill aphids?
To supplement, killing aphids with soapy water has many other benefits for your garden.
1. Low Toxicity
In addition to the fact that soapy water kills aphids, the solution is of least concern with regards to toxicity. Unlike other interventions used to kill aphids, once applied, soapy water does not produce a residual impact.
If you spray a bunch of leaves directly with soapy water, and then another insect—perhaps a beneficial one—crawls onto the sprayed leaf, it’ll not be killed.
2. Inexpensive to Acquire
Killing aphids with soapy water is a budget-friendly pest control option. If you’ve had to treat other pest problems, perhaps in your home or garden, you know how expensive things can get.
Using soap as an insecticide is easy to acquire and, in most cases, many homeowners already have a liquid soap that is safe to use.
3. Ease of Use
Who doesn’t know how to spritz water from a spray bottle?
This is one of the easiest methods to kill aphids. Once your soapy water solution is put together, locate the perpetrators on your plants, aim and shoot to kill.
With all things considered, killing aphids with soapy water is a great option to look at. Since it’s effective, let’s explore whether it’s a safe option.
Is Killing Aphids with Soapy Water Safe?
Killing aphids with soapy water is safe.
But, as with every product or treatment you’ll use in your garden, it must be used for the intended purpose and according to label.
Since you’ll likely be making your own soapy water solution, there’s no label for you to follow. However, heeding a few guidelines will help to ensure killing aphids with soapy water is safe for your garden.

Killing aphids with soapy water is also safe as there’s no residual impact. This means that beneficial insects, unless directly targeted, will not be harmed.
To supplement, soapy water is relatively safe for plants. Why ‘relatively’? Some products are phytotoxic to plants. But, you can bypass this sort of sensitivity if you follow the suggestions.
Tips for Killing Aphids with Soapy Water
These tips should be followed if you want to successfully kill aphids with soap and water.
- Do not use more than 1-2% solution.
- Choose your soap wisely. Better success can be had with liquid castile soap, not the typical laundry detergent. Castile soap is vegetable-based, and with organic options on the market. So, if you have an organic garden, give this a try. Check out this article for more organic ways to get rid of aphids.
- Be mindful of when you apply your soapy water. Never add soapy water to your plants when the temperature is hot. It’s best to use your soapy water solution early mornings and late evenings when it’s cool.
- Spray directly to affected leaves and plants. As mentioned before, soapy water kills aphids by smothering. You have to completely cover them with the solution to get success.
- Always check to determine how your plants will react to a soapy water solution. Spray a small area of your plant (sometimes a leaf or two will suffice). If the plant begins to wilt or leaves transform to brown or yellow, that’s a sign of phototoxicity. If this happens, spray fresh, clean water onto plant leaves.
- In some cases, you can dilute your soapy water solution with more water if you deem it’s too strong.
