Which treatment will prevent migration better: thermal or chemical?(4 posts)
We are deciding between thermal vs chemical treatment. We share a wall with neighbors. The thermal providers say thermal is best at preventing the bed bugs from traveling across this wall which is 120-year old brick covered with plaster. The highly recommended chemical PCO says his treatment will prevent it better since some bugs that have recently eaten wont move towards the heat and may move away from it. The thermal folks say that the bugs won't flee the heat at all.
Only one room shares a wall but that room is infected.
What do you experts recommend? Thanks.
It all depends on who does the work really. Anything can go wrong in both cases. Chemical has a residual so if anything is not killed on day one you have back up. Once the truck drives away from the thermal treatment ... it has to be 100%
Many of the folks I work with use pesticides in combination with heat.
If there are masonry walls covered with real plaster then these areas may present a significant heat sink. That is an areas which is difficult to up to and hold the lethal temperatures. it's not imposible but can be difficult.
It does not need to be a one or the other method situation.
Given the choice, perhaps go with the professional you feel most comfortable with and who will stand behind his work.
You can also ask for referrals from satisfied customers if this would help you to decide.
Good luck, which ever you choose, I hope it owrks out well for you ! paul b.
I just wanted to second what the two PCOs here already said: it's less about the method and more about the application.
I live in a post WWII four-plex (very common construction in my part of southern California). I was the only unit infested. I had heat treatment. The bugs did not migrate.
Chemical treatments typically take longer than heat treatments, so I would think that if you're not being bait for the bugs during that time, in most cases, there's a slightly greater chance (and by slightly greater, I'm talking about a chance of .001 vs. .002 %) of the bugs migrating with chemical, but depending on the construction of your home, heat treatment may be slightly harder to do.
The PCOs who replied above, however, are exactly correct. A good chemical based treatment from a PCO who knows what he or she is doing with bed bugs is just as good at keeping the bugs from moving as a good heat treatment from a PCO who knows what he or she is doing. Part of that expertise is the PCO's ability to assess your home and figure out what's best for that particular situation.
Our lives would all be a lot easier if there were one or two foolproof ways to get rid of bed bugs that worked 100% of the time, even when administered by PCOs who are only semi-skilled to clients who are poorly prepared and who are what medical folks would call non-compliant with the preparation and treatment. However, human beings are fallible.
The advice that I give out most often is as true in this situation as it is in most other scenarios: the best thing you can do to get rid of your problem as quickly, completely, and cheaply as possible if you look at the long run is to hire the best, most-experienced with bed bug PCO in your area whose treatment philosophy most closely matches your own. And prioritize those criteria in that order:
1. best, most-experienced with bed bugs PCO is the criterion that takes priority.
2. whose treatment philosophy matches your own is the secondary one if you've got more than one PCO who meets the standards for criterion #1.
Search the boards to see if there are reviews here of the PCOs you're considering. If not, look for reviews on places like Yelp or Angie's List. If there's nothing there, you might post here to see if anyone here knows anything about the PCOs in question. (Yes, as with all internet sources, it's up to you to look for any bias in what's reported in terms of online reviews, but sometimes you can find useful information that way.)
Hope that helps a bit.
