Each canister shell has a large mouth opening for filling the canister and a hose connection for applying water pressure to one of said canister halves while allowing flow from the duplicate hose connection on the other canister half for the purpose of spraying. An additional feature of this invention is in the operation thereof wherein the over-all canister need be filled with insecticide solution once and from then on the container has the proper amount of water therein for future mixes without any refilling as a separate step.
