Mice control and openings in basement

[Chris Miller]

Hi everyone. Have a rental property, older 1925 row house in philadelphia that we renovated and rent out. Tennant has been in about 6 months and in Jan she is now noticing mice. Going to call an exterminator to take care of the mouse but also want to permanently stop future occurances. 

My question to other landlords, what preventative steps do you take to make sure pests do not get in ? Im assuming they are coming from basement and i do notice the back end of basment wall has an opening where they built an extension so assuming i would need to close this off and seal up all cracks/openings to ensure this does not happen again.
