Instructions for applying Mosquito Barrier:

Mixing & Spraying
Mix 1 gallon of Mosquito Barrier with 99 gallons of water and mix well. Best results are achieved by spraying 25 ounces of Mosquito Barrier in 20 gallons of water per acre. Use a droplet size of 350-400 microns or medium size mist (not large droplets) and cover all grass, standing water, shrubs, into tree branches up to about 12 feet and under porches and decks where water may be standing. Spray the shorelines of creeks or ponds (mosquitoes are also born in mud). The best spraying time is 8AM and 11AM or late in the afternoon 5PM to 8PM. Avoid spraying in the heat of the day and do not spray if rain is predicted within 48 hours.

Mixing & Equipment for Smaller Jobs
Recommendations for mixing of Mosquito Barrier to use in Spraying Equipment for smaller jobs: Canister type sprayers hold 1, 2, and 3 gallons of liquid. Canister sprayers must be pumped up with air pressure and they have a wand for spraying. The rule of thumb for mixing Mosquito Barrier into canister sprayers is: mix 1 1/2 to 2 ounces of Mosquito Barrier to each gallon of water, under normal mosquito infestations. Adjust spray to medium fineness, not heavy droplets. When there is a heavier than normal mosquito infestation, use 3 to 4 ounces of Mosquito Barrier to each gallon of water. Fill the canister with water, mix well and spray. Equal amounts of Mosquito Barrier along with Canola, Soy Bean, or Cotton Seed oils, (the recommended vegetable oils) can be added to each gallon of water, to suffocate mosquito larvae in standing water and puddles.

Garden hose-end sprayers are not recommended because they are generally very inaccurate and the droplet size is larger than desired. However, if you still prefer to use a Garden hose-end sprayer, there are two types. One type has a dial for ounces per gallon and the other has no dial. For both types fill the container with undiluted Mosquito Barrier, on the dial type, set the dial on 2 ounces per gallon, or 4 tablespoons per gallon.
