Yes, Petcor Flea Spray does keep working after it has dried. Petcor will kill adult Fleas on contact, but continues to protect by preventing flea eggs from hatching for up to 30 days. You should continue to apply as needed to kill adult fleas found on your pet.
According to the product label for Petcor Flea Spray, it does say that some cats may be sensitive to products containing pyrethrins. Excessive salvation and ear and paw flicking may occur; however, these effects are temporary and not harmful. May cause dermal sensitization (skin allergy). If there are concerns about using certain products, we would recommend reading the product label in full and/or contacting a veterinarian.
Petcor would not be the appropriate product to use on carpets or furniture for flea control as Petcor is specifically for applications directly to the pets themselves. If you wanted a product to treat carpets you could go with either Precor 2000 Plus, or the products in our Indoor Flea Kit.
You want to allow the dog's fur (treated with Petcor) to completely dry before allowing the children to play with him.
Yes, Petcor is a good option for treating ticks on dogs.
We apologize for any confusion. Petcor Flea Spray contains natural Pyrethrins which have no residual properties, which is what that answer is referring to. There is no residual to continue to kill anything. (S)-Methoprene (which is an IGR only) will remain for a time though it does not kill anything directly. It only prevents young from maturing into reproducing adults. As a result, any pre-adult fleas that then contact the animal it is applied to will not be able to mature. If you want to continue to kill adults that get onto your animals, then you will have to reapply as needed.
Per the product label Petcor Flea Spray can be reapplied as often as weekly of your pet becomes reinfested with adult fleas for outside sources. Please let us know if we can be of any more assistance.
Petcor Flea Spray can be applied weekly for infested pets and preventatively every couple of months.
Wearing gloves is a safety precaution recommended by every manufacturer when dealing with chemical products such as Petcor Flea Spray. No one knows how every person will react if contact is made so it is recommended to avoid skin contact as much as possible, wearing gloves is part of that.
