If you're saying that unloading half a can of Pif Paf, RAID or similar "wet" solutions is not working on them, then i suggest you grab what you can, and run for your life!
I had them when i lived in the Marina - on the 17th Floor!!! i thought they only hung around near the ground, but obviously not......
I found that spraying a little demarcation line around them, on the tiles, just to keep them contained, and then unloading a good quantity directly onto them, and any holes they appear out of, does the trick.
Then just sweep the bodies up and move on.
Boiling water always used to work, too.
