I put just about a teaspoon in a water bottle or mini spray bottle when I get at my destination, and put just a little water, like 1/2 a cup to one cup water and keep it handy for my stay. Put some on a rag or towel and wipe stuff down, including pouring a few drops of the diluted mixture down the p-traps in the shower drain for sneaky cockroaches that could come out at night.

Mattress manufacturers use this during manufacturing. Also, many outdoor clothing companies apply it to their clothing to kill ticks and mosquitoes. It repels AND kills bugs, better than deet. All my travel clothes and my satin pillow case cover I travel with are sprayed with permethrin. Last numerous washings. And yes, it kills and repels bedbugs. Good luck.
