Kills Insects on Contact
Kills Destructive Insects on Contact Safer® Brand Insect Killing Soap uses potassium salts of fatty acids to kill soft-bodied insect pests on contact. Potassium salts of fatty acids work by weakening and breaking down the protective outer shell of the insect, ultimately triggering dehydration and death.

Potassium salts of fatty acids are derived from the natural acids found in animal fats and plant oils. Simply spray your plants at the first sign of insect damage, and apply every 5- 7 days as long as insects are present.

  • Aphids
  • Mealybugs
  • Earwigs
  • Whiteflies
  • Grasshoppers
  • Harlequin Bugs
  • Leafhoppers
  • Mites
  • Plant bugs
  • Psyllids
  • Sawfly Larvae

Use on Variety of Plants
For Use on a Variety of Plants Insect Killing Soap is gentle enough to use directly on your plants to keep them pest-free. Potassium salts of fatty acids targets the soft-bodied insects attacking your vegetation, giving your plants the opportunity to thrive.

Mix this concentrate and use Safer® Brand Insect Killing Soap on flowers, fruits, vegetable, houseplants, trees, shrubs and ornamentals. Gentle enough to be used up until the day of harvest and the solution will not persist in the environment after application.

How To Use Insect Killing Soap It’s important to thoroughly drench all plant surfaces (including and the bottom of the leaves). Continue to spray the solution to the point that it begins to drip off the plant.

As a general rule, much like watering, do not use this product when the sun is at its highest point in the sky or when temperatures exceed 90 degrees F. Application during these times could cause wilting or browning of the leaves. Since Safer® Brand Insect Killing Soap is a contact killer, multiple applications may be needed for full control.

How to Use
Concentrate Solution
An Economical, Easy-to-Mix Solution This 16oz bottle contains a concentrated insecticidal soap solution that creates over 48 times that amount in usable insect-killing spray. Simply mix a small amount of concentrate with water as directed until you have the desired amount of insecticidal soap.

Store any unmixed concentrate in a cool place for later use. One 16oz bottle of concentrate makes up to 6 gallons of solution, which is the equivalent to 24 bottles of our ready-to-use spray! This entire bottle will cover up to 1,600 square feet of plantings.

Compliant for Use in Organic Gardening Organic gardening is a rewarding hobby offering economic and health benefits. An organic gardening regimen saves you money by creating sustainable gardens that feed the soil where gardens grow. This produces greater yields and reduces the need for fertilizers and pest controls. Increased organic matter in your soil reduces erosion and conserves water. Growers say the fruits and vegetables produced in organic gardens are often more flavorful and nutrient-dense.

Safer® Brand Insect Killing Soap Concentrate has been third-party reviewed for use in organic gardening by the Organic Materials Review Institute to carry the OMRI Listed® seal, which means it has been deemed compliant for use in organic gardening by the USDA’s National Organic Program.

Smells ok By AphidPredator

I just bought this stuff (on Amazon) to use on my indoor China Doll tree that has survived many infestations. I'd only been using diluted rubbing alcohol to kill spider mites with, but my poor tree got eaten as soon as it regrew small branches. So far, all I have done is mix the stuff and spray it on, which I did outside and in the evening (AZ sun is unforgiving here). It doesn't smell all that bad, not what I had expected. I will write a follow-up in a week or so. Really hoping this does the trick; China Doll plants are hard to come by here and are my favorite houseplant! Right off the bat (or right out the box), I removed a star, due to the "peel here" instructions on the back that do not include instructions (I peeled the label off, there was no 2nd layer to peel).

Great product By KJ

This product will take care of spider mites and aphids without any harmful residuals. It is a contact product so keep a hand sprayer close and spray them when you see them.

Great product By Redsoxbengal

I bought this product because I started to get mites on my tomatoes. I've sprayed it once and it worked like a charm. No sign of them, but if they do come back, I know what I'm gonna use.

Excellent product By James

I've had a problem with spider mites on my indoor plants for years. This product showed exceptional results after the first application. I did a second application 3 days later, to take care of any mites I had missed, and found a few, but I expected that. The second app. seemed to have wiped them out, but I'm spraying on a weekly schedule now, using this product, in rotation with 2 other sprays, in an effort to keep from having the mites develop an immunity. I'm very happy with the results.

In the world of pesticides and repellents the words "organic" and "natural" are often mistakenly used to replace one another. Understanding product labels and certifications can help clear up the confusion.


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»
