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.

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.

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.

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?
