Essentria IC3 is an organic insecticide and will last only approx 2-3 weeks due to natural ingredients will break down quicker in outdoor elements. You will have better results using a synthetic pyrethroid insecticide such as Suspend SC. Suspend SC will last you 30 days outside and 90 days on the inside of the home. Spraying the perimeter of the home 2-3ft up and 2-3 ft up from the foundation and focusing on windows, doors, and entry points to the home will help. You also want to trim any bushes, shrubs or trees back from touching the side of the home.
Please watch the video on the Suspend SC for application tips and directions.
Essentria IC3 and other liquid concentrates should be used within 24 hours of mixing. If left longer, it could damage spraying equipment and they loose their effectiveness
Essentria IC3 Insecticide Concentrate is not specifically labeled for carpet beetles.
