I want to use Picaridin, will washing my clothes and the camping gear keep my cats safe when I return home?

My cats are not coming on our camping trip and they don't have access to the part of the house where we keep our camping gear, but they will be around our clothes when we get back.

We are only going for 3 nights and won't return home until four days after that, will just washing everything be enough to keep our cats safe?
