They’re everywhere! You have to do the whole building!!
These are common statements that we hear all the time, and sometimes they are actually true!
We have successfully eliminated pharaoh ants, bed bugs, mice, silverfish and cockroaches from entire buildings. However, in most cases all you need to do is inspect and possibly treat the units directly touching the one reporting the issue. That is the units above, below, beside and possibly across the hall should all be inspected, then treated depending on results of the inspection and which pest is being dealt with.
|Pest||Need to inspect surrounding units?||Need to treat surrounding units?|
|Bed bugs||Yes, always||Yes, Very common|
|Mice||Yes, always||Yes, Very common|
|Rats||Yes, sometimes||Highly unlikely|
|Cockroaches||Yes, always||Yes, Very common|
|Pharaoh Ants||Yes, always- and treat them too||Yes, Very common|
|Silverfish||Yes||Yes, Very common|
|Stored Food Bugs||Rarely||No|
|Fabric Moths||Sometimes||Yes, but rare|
The key is to be aggressive initially so that you surround the problem you know about, and eliminate it before it gets out of hand. Just responding to complaints and not doing proactive inspections are great ways to end up having a much bigger problem down the road.
