If a bit of water touched the Precor IGR Concentrate treated area, it should be fine. It will not reactivate the product. If the carpet was steamed or shampooed, then some of the product will have been removed.
Precor IGR Concentrate should NOT be applied to animals at any dilution. It is not labeled for a safe usage. We do carry products such as Martins Flea, Tick and Mange Dip. When following the instructions on the product label for Martins Flea, Tick and Mange Dip it should not harm your dog if he licks after drying. Sensitivities may occur after using ANY pesticide product for pets. If signs of sensitivity occur, bathe your pet with mild soap and rinse with large amounts of water. If signs continue, consult a veterinarian immediately.
Precor IGR Concentrate should be mixed with water only. A boric acid product can be made separately and applied to voids, cracks and crevices, and other listed areas once the Precor application has completely dried. Be sure to follow the label instructions for each product.
Precor concentrate only helps stop the reproductive cycle of the fleas so if the professional only sprayed that before that is likely part of why you haven't seen a huge difference in flea numbers. If you are looking to spray inside the home you would want to use a product like Fenvastar Ecocap to mix with the precor and spray floors, baseboards, crevices, rugs and any other areas where fleas may be present. Once you spray the mixture of those two products down, let them dry completely before you or any pets or children re-enter the home. You will want to continue vacuuming every other day for 14 days and then on the 14th day you will do a reapplication of the same two products. You should not be spraying any more frequently than once every 14 days for flea control. The products will continue to work and slowly kill them out over time. If you have pets in the home make sure they are treated with a flea topical or collar and the outdoor areas around the home they frequent are treated as well.
