Lease says I’m responsible for my own pest control. My a/c has been messed up before because somehow the ants are getting into a hose or something in the outside unit. He’s called repair men twice and paid for it to be fixed, but this time he says he won’t because if it’s ants again, it my fault. But I DID do pest control – I sprayed around the unit and have used ant granules in the yard around the unit. So, is there anything I can do, or am I now responsible for paying for pest control and a/c repairs?
