I've lately had a problem with book lice (psocids) in my kitchen and bathroom cabinets (though, of course, they are also in many of the hundreds of books my significant other owns.) The man at my country extenstion office says that if I reduce moisture, that will help get rid of them, but he says that a dehumidifier probably won't work because it's only dehumidifying the air, not the physical objects. I really don't want these in my kitchen or bathroom (they laid eggs on my cutting board that is built into my kitchen cabinets.) I live in a rental apartment in Los Angeles. What can I do to remove moisture from inside the cabinets? I'm 95% there are no leaks (there was one about six months ago that I promptly got fixed.) There is an exhaust fan in the kitchen, but it doesn't appear to me to be vented outside (maybe it is and I can't tell?) In the bathroom, there is no fan, just a window and I leave a small fan on the counter on for over 12 hours a day. In the bathroom, at least, I feel more comfortable using poisons to kill them. Would a dehumidifier help? How about something like DampRid (which I already use in my bathroom--I had a problem with mildew on the ceiling, I cleaned it with bleach and repainted with a mildew-resistant paint. It was attracting ants--which will again be a problem if I have to leave the window open all the time.) Thanks for any advice.
