Rental property with Mice

[Sal Flores]

Hi, BP'ers 

Looking for an advise

One of my tenants just told me that the property they have been renting for more than a year, that they started to have mice over the last month, they putted some traps and have caught 3 mice, they are saying still hearing like there are more, and apparently they found some holes in walls.

Apparently a neighbor in front have the same problem

I reviewed the lease agreement and does not have any term of saying who is responsible for pest control, besides I have expressed verbally since the beginning, tenant is responsible for pest control. 

In some point I am worried how the mice can destroy the property and/or the problem can be arised.

Any advise please

I will appreciate any information it can be provided

Thank you

Sal
