Envion is a water dilutable concentrate containing 2.52 lbs Permethrin and 2.52 lbs Piperonyl butoxide per gal. Diluting with water saves on unnecessary mineral oil being sprayed into the environment. Envion does not phase or separate once in solution with water, so what's in the top of the spray tank is the same as what is in the bottom for uniform spray throughout the tank.
Mosquito control districts get the cost advantage of a concentrate and do not have to purchase, stock and mix costly diluent oils.
Available sizes: 2.5-gal, 30-gal, 55-gal and 275-gal totes.
