Inside or outside or both?
Can you please explain where you want to put flea and tick application.
Hi E: If the fleas are on your pets, you can wash your pet in a bath of Blue Dawn dishwashing soap. Let the suds sit on for at least 5 minutes, and rinse off very well. Then, blow dry your pet on a white towel and you will see the dead fleas fall off. You can also make a spray of a couple drops of Dawn and water and spray around your house. This should kill the fleas. Fleas live about 2 or 3 months. I have had very good luck with Frontline, just be sure that the package DOES NOT have an expiration date. Frontline doesn't have an expiration date, but the knock-offs do. Get the right dose for the size of your pet, you don't want to over dose or under dose your pet. When you vacuum your floors, empty the tube, if that's the type of vacuum you have, or remove the bag and put the whole thing in a plastic bag and throw away outside. The fleas will live in the vacuum and then sneak out and start living large in your house. Just know that you will have fleas for at least a month or so because the eggs will hatch and you will have fleas from them and those fleas will lay eggs, and finally, the end will come when there are no more eggs. So, it's not going to be an overnight or over week fix, sorry. Good luck
