I can understand your frustration. Be certain you have fixed all water leaks and that you've cleaned thoroughly. Throw the vacuum contents out outdoors. I have had great results mixing Borax laundry powder with sugar to kill them. Boric acid as mentioned above will work also. Mix 50/50 and place where you have seen them. Takes a bit of time but within a week or so they should be gone.
