Crossfire Bed Bug Concentrate kills within 5 minutes of contact and leaves a 30 day residual. This cannot be used on clothing. If treating for heavy infestation or active bed bugs, it is recommended for best results to use a combination of products to effectively treat all the areas where bed bugs hide. Bed bugs require repeat treatments every 7-10 days until you can go 30 days without seeing any signs of bed bugs or without anyone getting bit. Please view the Pyrethroid Resistant Bed Bug Kit that contains Crossfire, Cimexa Dust and Bedlam Aerosol. View our Bed Bug Treatment Guide for step by step instructions on a successful treatment program.
