Bedbug in a multi family

[Marita Jojo]

I have a multi family with 6 units and only one tenant keeps complaining of the bedbugs. The unit was treated professionally twice but the tenant is worried about other units. Do you have to do the treatment of all units in this case ?

When I bought my first 4-unit the upstairs units were vacant. About three months in I had rented out one of the 2nd floor units but the tenant hadn't moved in yet. 

I was showing the last vacant unit to a tenant and after the showing one of the downstairs tenants told me they have bedbugs. They bought the powder, mattress covers, etc. and I bought some non-toxic bedbug spray off Amazon that was rated highly and had it mailed to their unit. 

Before heading back out of town (I lived in Los Angeles at the time) I bought a gallon jug of bug killer spray from Lowes that stated it killed bedbugs and sprayed the heck out of the two vacant apartments and the carpeted hallways as well. 

The issue was resolved as this occurred four years ago and there were no other bedbug complaints since.
