Can I apply diatomaceous earth to the tops of carpets after using Precor IGR concentrate?
Yes, you can apply Precor IGR, allow it to fully dry, and then apply Diatomaceous Earth. Diatomaceous Earth is labeled for fleas and other crawling insects and will definitely help but because it is slow acting you will most likely need to treat with another product first to help get the flea and ticks under control. DE takes about a week to kill an insect and in that time the insects can continue to bite, breed and lay eggs. You can apply Food Grade Diatomaceous Earth under carpet. We recommend to go ahead and vacuum the carpets. This help to bring the fleas up to the surface and in contact with the D.E. You want to stick with applications to, cracks and crevices; behind and beneath appliances, cabinets, and garbage areas; around sewer pipes, drains, foundations, and windows; in attics and basements; on patios; along baseboards; under carpeting; in and around pet bedding and sleeping quarters. Please check out our video How to Get Rid of Fleas. We would recommend that you treat with a product such as Aline Flea Insectcide with IGR which will give you a fast knockdown of the biting adults and residual control of the developing fleas and ticks. It is very important to vacuum immediately before the treatment and every day or every other day for the following 14 days. At the end of the 14 day period you will most likely need to re-treat to get rid of any stragglers. You must also treat all of your animals with an approved flea/tick product so that you are not re-infesting the house. Precor 2000 is safe to use in a house with pets as long as you follow the product label. All pets should be out of the area that is being treated and they can return as soon as the area is dry.
