Glue traps work great for small criters.
Beware. Flee collars are a product that the evil chineez copy, fake and resell to unsuspecting Americans. They do not work. These flea collars look very identical and the packaging is very identical to the real ones. Beware of ebay or amazon deals as these are usually the fakes. If you can message the seller you can usually detect if they are real Americans or write in the sloppy poor grammar as you would expect from that part of the world. Run away.
The Bayer collar is effective with fleas, but the cats seem to stick around still, so not sure other animals would be driven away, just fleas.
