How do I get rid of roaches??

[Ryan Kawash]

Hey guys, I recently closed on a duplex.  I renovated one of the units that was vacant upon buying and got a tenant in there.  6 days later, she sent me pictures of roaches in the unit.  Is there a way to permately get rid of roaches or what's the best way to prevent them from coming back??  Let me know thank you!!
