Reapply as necessary, but not more than twice per week. Applications must be at least 3 days apart.

Thoroughly clean spray equipment before using. Shake concentrate well before diluting. When diluting, first add approximately 1/2 of the water to the spray tank and then add the proper amount of concentrate. When emptying the bottles, triple rinse with water, shake well, and add the rinsate to the spray tank. Add the rest of the water and agitate the sprayer thoroughly. Agitate sprayer occasionally during use to ensure even mixture.

Spot Application Apply at the rate of 1 second per 2 square feet or to the point of runoff. Direct nozzle approximately 12 inches from surface to be treated. Apply directly on insects in these locations when possible. Limit individual spot treatments to 2 square feet.

Residual Control • 90 days for fire ants on painted wood, unpainted wood, and ceramic tile • 59 days for mosquitoes at 0.050% rate on leaf surfaces • 30 days for mosquitoes at 0.025% rate on leaf surfaces • 14 days for scorpions at 0.050% rate on porous surfaces

This product can be converted to a foam and the foam used to treat structural voids to control insect and arthropod pests in walls, under slabs, or in other void areas. Apply as a dry foam (approximately 25:1). Fill void with foam so that all surfaces are contacted. Mix end-use dilution with manufacturer’s recommended volume of foaming agent. Use the specified rate suspension converted to a foam to achieve the desired foam expansion ratios.

Perimeter Treatment Treat a band of soil 6 to 10 feet wide around and adjacent to the building. Also treat the building foundation to a height of 2 to 3 feet where pests are active and may find entrance. Treat other insect entry points such as doors; windows; under siding, decks, and eaves of structure. This product may be applied in compressed air, backpack, or power spray equipment. An application rate of 0.5 to 1.0 fluid ounce concentrate per 1,000 square feet is desirable. Apply in a sufficient amount of water to adequately cover the area being treated. Application should be made in such a manner to limit dripping and runoff on structural surfaces and plants. Alternate directions are to use 4 to 8 fluid ounces per 50 gallons of water.

Active Ingredient

Alpha-Cypermethrin 3%



Two innovations, BASF reports, differentiate Fendona CS insecticide: a purified active ingredient called alpha-cypermethrin that’s four times more active than regular cypermethrin, and an advanced encapsulation technology that produces smaller and many more capsules, and facilitates diffusion of the active ingredient from inside the capsule into the lipophilic cuticles of arthropod pests. “The potency and efficient delivery of the active ingredient means you can use significantly less to achieve superior results, and the smaller cap size means a greater number of capsules are distributed over an area, increasing the chance of contact with the insects.”

The unique encapsulation offers other benefits as well. It can reduce paresthesia; the skin irritation technicians can experience when handling pyrethroids, BASF said. It protects the active ingredient from rain and the sun’s UV rays for greater durability. It also does not absorb into porous surfaces, which increases its residual.
