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.

Q.We have Aquaponics. The fish are below our plants infested with aphids. Is the product: Safer, Insect Killing Soap safe for our fish? Thank You, Sue

This product is not recommended for use in hydroponics or around aquatic life.

Q.Anything for the Spotted Lantern Fly ? Pennsylvania is swarming.

Currently, we do not have any product recommendations for the spotted lantern fly.

Q.Bought your Safer brand Insect killing soap concentrate. The instructions are NOT on the label or under the peel off (which is blank - why would you do that ?) What is the correct dilution ratio for houseplants ?

The recommended dilution rate for indoor plants is 5 Tbsp of concentrate per gallon of water.
