Does Diatomaceous Earth 85% work well on fleas and ticks in the house?

We take care of several Feral Cats and have approximately 11 in house and a dog. We have been using another product for sometime but it seems to not be working anymore. We need help fast and something that will not harm our indoor animals. Thank you for your time, Janet


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. We would recommend that you treat with a product such as Precor 2000 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.
