This is for a rental unit, so I'm trying to keep the cost low, while also sealing it away from silverfish. I have very fine steel wool on hand as well as a tube of DAP ultra clear flexible all purpose sealant.
Imo, duct tape the shit out of that. I had a similar hole in my apt, and I just did maybe paper over it and then long strips down, layering them a bit, and then over, and it all gets a bit fucked in the middle, but point being you can get a seal. Cost is a half a roll of duct tape
I'm actually a tenant trying not to deal with my landlord. But I fully agree with your take on it.
