The amount of Tandem Insecticide a quart size bottle will make depends on the concentration it is used at. If you use the 0.065% concentration, a quart size bottle will make about 58 gallons of solutions.
How well does Tandem work on controlling mesquitos in the yard and in mulch?
A
Tandem works awesome in treating Mosquitos in yards and mulch. It is microencapsulated so the active ingredient is protected from the outside elements, therefore offering a more successful kill. It is also specifically labeled for use indoors and out, in lawns, shrubs, etc.
