Doktor Doom Spider Mite Knockout is a powerful spray that can be used indoors or out. It's safe to apply on food crops, such as tomatoes and other vegetables, up to one day before harvest. 

It features a 0.20% formula of the naturally-occurring insecticide pyrethrin which is a highly effective substance to control insect infestations on plants. Pyrethrin is approved for organic gardening (for restricted uses refer to OMRI for more information).

Does NOT contain the synergist Piperoynl Butoxide (PBO) which can cause plant damage (phyto-toxicity) as it clogs stomatas. Stomatas are the pores that plants use to create photosynthesis. When clogged, your plants suffer reduced size and fruit production.

Doktor Doom Spider Mite Knockout is ideal for:

Aphids
Spider mites
Whiteflies
Leafhoppers
Japanese beetles

Comes in a 16-ounce aerosol can which sprays in all directions - even upside down for hard-to-reach areas. Apply it to the bottom of the foliage and then use a Doktor Doom Fogger. Fog your growroom 3 to 4 times over a period of 12 days for complete spider mite eradication. Remember, spider mites lay their eggs when you try to kill them, so repeat applications are needed to win the war!

"One-Two Punch" package includes 1 can Doktor Doom Spider Mite Knockout AND 3 cans Doktor Doom Fogger (2.47 oz) for complete spider mite eradication. Saves 15%!
