Greg from Dayton Texas writes
I have a fire ant mound around the base of my plant. I normally mix 4 oz pre gallon whenever I spray my yard and around my house slab.
Bifen I/T is not safe for use on or around any edible vegetation. Bifen is also only used at 1 (ONE) ounce per gallon of water and should never be used at a rate higher than this for multiple reasons. If you need to treat a fire ant mount around edible plants such as grapes, you can either use boiling water to drench the mound directly and kill them on contact, or go with a product like Sevin Insecticide which is for controlling insects in garden areas.
