Safer® Brand Insect Killing Soap (Insecticidal Soap)

This 16oz Concentrate will make 6 gallons of OMRI Listed® insecticidal soap to eliminate soft-bodied insects. One bottle makes the equivalent of 24 Ready to Use bottles!

Safer® Brand insect killing soap utilizes the power of potassium salts of fatty acids (insecticidal soap). The potassium salts weaken the insect's waxy protective outer shell. Apply every 7-10 days when insects are present or as needed to prevent further damage.

Safer® Brand Insect Killing Soap breaks down into its natural elements within 7-10 days, and will not persist in the environment.

  1. SHAKE WELL. For best results use freshly mixed solution.
  2. DO NOT use on new transplants, newly rooted cuttings or plants stressed by drought. Avoid application when temperature exceeds 90° F.
  3. Apply when insects or signs of their damage appear. Thoroughly wet all surfaces of infested foliage and branches.
  4. For full instructions depending on indoor/outdoor use and specific plants and insects, please refer to the Instructions link to the left.

best on the market By kathyw
I have been using Safer for about 20 years to safely kill fleas in my house, without harming my animals, or myself. Great for people "allergic" or toxic to traditional pesticides. No chemical residue. I'd recommend it to everyone.

Really like this product! By Vee13
I've been using this product for several years, now and really like it. I had scale on my fig trees and after spraying the scale with alcohol to start the killing process, I sprayed it with the Insect Killing Soap and the scale died quickly, though I didn't see anything on the label about it being for scale. Can't get better than that.

In comparison, when I had run out of this soap, I bought a different brand from Home Depot. or Lowe's that was also an insect killing soap and it didn't do as good a job, though it WAS listed to kill scale. I'm sold on Safer Brand products.

While this killing soap works well, I believe pesticide works better, I actually prefer the faster more guaranteed methods of killing bugs.

I like the idea of an organic pesticide vs chemicals. I mixed this in an empty 32oz spray bottle to use on my vegetable plants. So far it seems to be working well. I wish the mixing directions were more practical. I had to estimate how much I needed for my type of sprayer

This stuff kills all sorts of aphids and malathion-resistant whiteflies. The best part is that you can harvest the same day, because it's non-toxic. You can rinse it off easily, if you find the taste disagreeable. And that's the bad part. It washes off instantly with rain or overhead irrigation, unlike systemic pesticides.

I bought this a few months ago along with some neem oil when I noticed some thrips and springtails on my African Violets. I took care of them at first using the neem oil in the soil and picking off the bugs with a q-tip drenched in alcohol and didn't notice them for awhile. Long story short I ended up moving along with my African Violets and herb sprouts and seedlings about a month ago, got busy and forgot about the bugs. A day ago I noticed them all over my violets and not wanting to mess around with waiting on the neem oil since there were just too many to pick off by hand with the alcohol and not wanting them to get to my baby plants, I mixed a small batch of the solution (eyeballing it...I probably got more soap than I should have in there but oh well now it'll get down into the soil too) and sprayed down my violets. All the little springtails, thrips, and aphids (those guys popped up a day or so ago as well) were flushed out and died on contact. I really like this stuff because I own birds and am always leery of anything chemical based, but there was no vapor aside from the spray that fell instantly on the plants and I even stupidly did not wear gloves and ended up spraying my hand while I was holding leaves and flowers out of the way to get all areas of the flowers. My hand is fine after washing it for ten minutes in dish soap as a precaution and my violets don't seem to mind the soap didn't burn, wilt, curl, etc. I'll be using this stuff in the future anytime I have an issue with bugs that I can't deal with by manually pulling the annoying little things off my plants. Glad the companies finally got with the program and made something actually safe to use indoors for a change!

Although we haven't had a chance to use it yet as we live in the north country, I've used it before and have always had excellent results.

Tips for Using Insect Killing Soap

SHAKE WELL. For best results, use freshly mixed solution. Use soft water whenever possible.

Flower and bedding Plants Growing Outdoors and in Home Greenhouses:

Including foliage plants, roses and succulents.

Apply when insects appear. Take care to thoroughly wet all infested surfaces. A second application should be timed to control newly hatched young. Repeat weekly as needed up to three times.

NOTE: Do not use on bleeding heart, gardenias, jade plant, lantana, lilies or sweet peas. Some varieties of azaleas, begonias, camellias, fuchsias, gardenias and impatiens have shown sensitivity. If wilting occurs within a few hours, rinse with clean water supply. Test on chrysanthemums for varietal sensitivity and do not apply to open blooms.

Ornamental Trees and Shrubs:

NOTE: Do not apply to chestnut, Japanese maple, mountain ash or Colorado blue spruce. Do not apply to ornamentals stressed by drought or when tender new foliage is present. Do not apply to evergreens during drought or when tender new foliage is present. Do not apply when temperature exceeds 90°F. Test on arborvitae, Eugenia, euonymus for varietal and drought sensitivity.

Vegetable Growing Outdoors and in Home Greenhouses:

Apply when insects first appear or when damage occurs. Spray to wet all infested plant surfaces. One gallon of spray covers approximately 850 sq ft of growing area.

For most pests, repeat application after several days to eliminate newly hatched individuals. Repeat at weekly to biweekly intervals up to three times. Do not make more than 3 sequential applications over a two-week period.

NOTE: Do not apply during heat of day or when temperature exceeds 90°F.

Fruits and Nuts:

Spray when insects first appear or to prevent damage. Apply to achieve thorough coverage of infested foliage/branches. Repeat at weekly intervals as needed. Avoid spraying when blossoms are present.

Indoor Plants:

Apply when insects or signs of their damage appear. Take care to thoroughly wet all surfaces of infested foliage and branches.

NOTE: Do not use on Crown of Thorns and test other euphorbias for phytotoxicity before full-scale application. Do not use on dracaena, delicate ferns, dieffenbachia, ornamental ivies, palms or succulents without testing.


FAQs About Insects in Your Garden


Q: Is a spider mite an insect or is it actually a spider?

A: Spider mites belong to a class called arachnids, to which spiders also belong. They are not actually insects. They do cause plenty of problems for plants, however, unlike their larger relatives. More»


Q: My cabbage and broccoli plants are being eaten by bugs that look like they have a colorful shield on their backs. What are they and how do I get rid of them?

A: These pests are known as harlequin bugs. Products containing Insecticidal Soap (potassium salts of fatty acids) and Pyrethrin are very effective on these nasty pests. More»


Q: My neighbor told me I have scales on some of my ornamental plants. What are scales and how do I get rid of them?

A: Scales are tiny insects that attack many plants, sucking the sap or juices from the plants and plant leaves. Insecticidal sprays and Neem Oil products are effective in controlling these pests. More»


Q: Isn't "insecticidal soap" just dishwashing liquid or soap added to water?

A: No. Commercially produced Insecticidal soaps sold at garden centers and similar retail stores are composed of potassium salts of fatty acids from plants and animals. They work by penetrating and destroying the outer shell or membrane of the insect causing it to dehydrate and die. More»
