How active are bedbugs during the day and does this painter's claim sound right? I did a heat treatment to a second floor apartment about 2 months ago. The tenants moved out a month later. I set Verifi traps in the apartment 3 weeks after I did the treatment and used double sided tape along the baseboards and bed frame legs. A few days ago the apartment manager tells me a painter, who was painting the now empty apartment, went home and his wife found 4 bed bugs in his clothes. The painter was informed the unit was treated for bed bugs before he painted. I went out and checked the traps and found nothing in the traps in the second floor apartment, however I did find bed bugs in the unit below, which has 3 people living in it. I also did a treatment to that apartment 1 week after I did the treatment for the second floor. So, I am catching bed bugs in the first floor and none on the second floor. Both have the same number of Verifi traps and were set the same day. I don't understand how a painter could get that many bed bugs on him and have them in his bed a few days later after painting a empty apartment with no signs of live bedbugs. Little off my question but I would like to mention I have used dogs in the past. One company I used alerted on 5 apartments - one never had any bed bugs and the other 4 were treated over a year prior to the dog inspection. This dog inspection was a year ago and there are still no signs of bedbugs in those apartments.
First on the dogs. This can be an extremely valuable inspection tool with properly trained dogs, but you mention some of the drawbacks to them. They are so sensitive that you may not be certain immediately if the dogs are hitting on active infestations or just the lingering scent of previous infestations. I think the proper protocol is to use the dogs to quickly find possible bugs, but then to do a very thorough visual inspection of those locations to verify whether or not the bugs are actually there.
