Look up DIATOMACEOUS EARTH on Google or your favorite search place! This will solve Most of your problems!!! Your carpets are probably rotted from the past infestation of beetles and their larva, you might want to put linoleum down anyway as money allows, with Ferrets in the house!! I also use allot of washable throw rugs. The fur-kids love rides on them and tunneling under them.too! I have had ferrets for 6 years and I have used DE for 3 years and have been insect free (ticks and fleas too)!! DE also can be eaten by human or animal.and will get rid of all kinds of nasty things! I buy mine at the local herbal store I pay $1.50 for a pound. Make sure you get food grade.not filter grade. Remember that it will kill ALL I repeat ALL insects. Good and bad. So be careful if you dust in your garden (you don't want to kill the bee's and lady bugs)! OK that's enough from me! If you research on line you will see what I say, and allot more! Good Luck!
