What they'll do is they'll start complaining about maintenance problems and pest problems, hey we have mold, mice, cockroaches, whatever - to try and get out of the lease. 

On and on.All of a sudden your perfectly maintained unit is requiring constant maintenance calls for pest control and the tenant is demanding toxic mold tests and maybe they're even calling the building department for code violations or the health department for pests. 

Landlord can pay for extra pest control if tenants are filthy and it needs more due to that.

She said there was a mold infestation in the laundry room, which there was months ago but I took care of it.

I've seen a lot of people who have their leases state something like "After 30 days, tenant is responsible for pest control" (was in a thread regarding possums)Does your lease say anything about that?

I just moved into a new apartment this weekend and the place was infested with insects.

The possums have not been inside the building, they have left droppings on the deck and they like to hang out in the fig tree in the front yard.My lease clearly says after 30 days the tenant is responsible for pest control.

Since your family is really low-tolerance, just hire a pest guy, is my advice.

I just can't see rats in a 900k neighborhood, but maybe with California's insane priced-out market 900k is a rat-infested neighborhood!

My properties are located in a drug infested ghetto.
