Sometimes small spaces make pesticide or other applications difficult for conventional sprays to reach or adhere to. Chemical foamers allow pest control products to fill small spaces like pipes, wall voids, and surfaces that liquids may not be able to reach.
Foam allows the pest control product to reach around objects, into cracks and crevices, and spreads wider and is able to come in contact with all surfaces better than a conventional spray. You will need special equipment to apply these foams. Some machines will convert the chemicals to foam, while other products need a foaming concentrate to help it convert to foam.
You can control the ratio of air to liquid in your foam with the foamer machines and your dilution rate. Dry foam has a high ratio of air to liquid that leaves limited residue, as it is mostly air with little liquid. Wet foam has more liquid than air and will quickly collapse and leave behind a residue.
Foams are especially effective for drains and pipes. Foams effectively fill pipe voids above the water line. It is able to come in contact with all wall surfaces and doesn’t dissipate immediately. Sometimes, this application method cuts down on fumes that can get into your home.
Not all chemical foams are created equal. Aqueous film forming foams (AAAF) are used in fighting fires and not for pest control. Because we are a do-it-yourself pest control supplier, the foamers we sell ARE labeled for pest control use. Defoamers are products that can be added to a chemical formula that keeps it from foaming.
