I suggest looking at the mount medix site. They have a host of green chemical sprays and solutions that will eradicate your problem. Not cheap at purchase, especially for me being in Canada but OMG cheap when looking at cost of what it saves. Like others have stated above, I put that shit on everything twice yearly. They have saver, protector and products to add when mounting. It also adds a nice smell to room after application, not raid/fumigate and leave smell. Its sold in many places throughout the US and shipped to Canada.
It works.
