As part of my effort to seal my new apartment against pest infiltration, I'm checking and sealing every possible opening from the walls where bugs live into my unit. One of the things that I'm concerned about are the openings in the wall for the pipes under the kitchen and bathroom sinks. These are concealed mostly by loose plastic rings (that appear metal until you look more closely) which, after looking behind them, reveal wall/pipe intersections that are kind of loose; you can clearly see space between the irregular holes cut in the wall for pipes. And the ring covering them is kind of loose. They're not stopping anything from getting through.
First of all, what are these rings called? The plastic ones are kind of cheap and flimsy feeling, and I'm considering getting new, higher quality ones.
Second, what the best way to seal these openings in the wall against pests coming in? Caulking, spray foam, putty, or something else? Aside from the material I should use, I know it would be best to seal them at the actual holes in the wall behind the rings, but the rings in the bathroom might not be removeable. I would need to cut the plastic ones off and I don't know how I can remove the metal one. The kitchen ones have a gap in them so you can slip them on and off easily.
