Hmmm. I'm not sure some of the terms I use should be published…
The electricians use a material that is a putty of sorts that is pressed into an opening where a wire may come out of a wall or meter socket. Early on, I have only heard of it referred to as Monkey $#*T.
I have purchased some of it at one time and said "I'll have some of that too" when another customer asked for it at the counter. It seems that plumbing supply house counter men did not know what I was talking about. This happened at an electric supply house
I have seen it on Supplyhouse.com https://www.supplyhouse.com/Rectorseal-81881-5-lb-Duct-Seal-Compound
called Duct Seal Compound
Since then if have also hears other brands call it Thumb Gum
But I believe you can clean it up by using Monkey Dung
Once you start to type M O N K E Y, the suggestion for Dung may populate the search bar. or Monkey Stuff
... You get the picture.
