You MUST clean you whole house and even the walls. You must go back every few weeks to spray the areas where insects have hatched because no matter what you use you do not kill the eggs. If you're still getting bitten you have probably missed an area where they are hiding, which is very easy to do. If you skip over even one crack they will continue to multiply and you will continue doing "the monkey" indefinitely.
Bedbugs are little vampires. If you see them that means they've sucked enough blood to multiply in size. If you want relief you cannot only kill the ones you see. You need to realize that there are more you cannot see than those you can see. You need to focus on killing the ones you cannot see. That means spraying areas where you do not see any bugs. Very important: take your mattress off and spray every crack in your bed. This website on bedbugs tells you how to clean and kill bed bugs. Follow their instruction with kleen free and you will rid your house of bedbugs without any pesticides and chemicals - Guaranteed! Once you're finished with the bedbugs you can use the rest of the clean free to clean almost everything in your house. Try to do that with a pesticide!
