[US-PA] Is it the tenants responsibility to clean up dead rats in the basement?

So me and my mom have lived in our apartment for at least 7 or 8 years and we've always had problems. The landlord really doesn't take care of this place. Our basement has been moldy for almost the whole time living here due to the giant holes in the walls letting water in when it rains and everything we had down there is ruined. We also had to basically fight them to replace the hot water tank after it broke (which the old one is still sitting down there next to the new one).

We never go down there due to the mold but recently we smelled something bad so we went down and found at least 3 big dead rats and rat poop everywhere. They are coming in through the giant holes which lead outside (you can see the holes on the outside of the house too) and there's holes that lead to the neighbors basements (it's an apartment complex) so I wouldn't be surprised if they have rats too.

We informed our landlord about the rats (and about our hot water tank breaking AGAIN) and she just told my mom to go clean up the rats because "it's a health hazard". No mention of fixing the holes or the hot water tank. Is it really our responsibility to clean up the dead rats? I highly doubt they are going to fix the holes or anything so it would be kinda dumb for the landlord to come out just to clean up some dead rats but it's also gross and they are only there because of the landlord not taking care of the place.

This is a genuine question because I really don't know. If it is our responsibility I'll do it and just hope I don't puke lol.
