Exterminator in Baltimore

[Raquel Thomas]

Could someone please recommend an exterminator.  My tenant has a roaches and lots of them.   I'd try to tackle the issue myself but its too much for me.   I also had an issue with roots growing in the line and it caused a problem with the toilet and sink on the first floor.  I had it cleared the same time last year and the exact same problem is back.  Any advice would be appreciated and a recommendation for a exterminator.  Thanks in advance.
