Yes — heat has to be able to flow freely through the space to do its job. Overstuffed closets and drawers can trap cool pockets and prevent the heat from reaching every hiding spot. Here’s what we ask:

  • Closets and drawers should be loosely packed, not jammed

Think of it this way: if you pack a dryer completely full of clothes and run it on high for 45 minutes, those clothes in the middle come out still damp. That’s because the heat couldn’t flow through. The same principle applies here — heat needs to move and penetrate, not just sit on the surface. A stuffed closet is no different than that packed dryer. Even a Thanksgiving turkey works the same way — pack the cavity too full and the center takes far longer to reach temperature than it should.

  • Too many clothes? Remove the excess, wash and dry them on high heat, then seal them in a fresh bag and keep them out until the treatment is complete.

We have a detailed prep sheet that covers everything specific to your home — David will go over it with you before the treatment day.
