TARGET PESTS: Mosquitoes and some other species of biting insects.

WHERE TO USE IT: Outside where you want to sit. Such places include decks, patios, pool areas, front porches, water front property, etc. Basically, you can install a Blocker where ever you want to keep away biting insects.

RATE OF APPLICATION: This will vary with several conditions. First, the air flow will have a big impact. If you have a steady air flow, that is, the air is moving in one direction all the time, you will be able to set one unit out just slightly downwind from where you are sitting. As the Conceal is released, it will prevent mosquitoes from being able to track the Co2 and octenol back to it's source. One unit would be enough for 1-3 people. Generally, as you add more people you have to add more Blockers. There is no definite formula to use since each person exhales these gases in varying amounts and local weather as well as many other factors will all combine to affect just how many will be needed. However, expect to use one unit for every 1-3 people. Furthermore, if you have air flow which is blowing in many different directions, you will need more units than normal. This is due to the fact that the random air flow will carry more of the Co2 and octenol so there will more routes for local mosquitoes to follow. A good general rule to follow is to try to place a unit on every side where mosquitoes might be active. If you are on a deck with two sides open you will probably need at least two units. If you are out in the middle of the yard, you will probably need 3-4 units. Remember that each cartridge will last 30-45 days and should be replaced as they dry out.
