Bed Bugs

A friend of mine recently had bed bugs. Thankfully, it seems they were caught early, and after two sprays two weeks apart they seem to be gone. Erring on the side of caution, I’m wondering when it will be safe to have my friend over to my place again, or to go visit him at his place? I know bed bugs aren’t exactly “contagious” but I’m concerned about one possibly hitching a ride on a jacket, tote bag, backpack, etc. And, of course, I don’t want to make my friend feel bad. I can’t find any good information online about this. Could you please help me out? Toronto

Don’t take/wear anything with you that you cannot fit into a large (contractor size) plastic bag after your visit. Then see https://tinyurl.com/4vhdwnkn for suggestions on using either heat or cold to kill any unwanted hitchhikers.
