Mark Sheperdigian on killing bed bugs in “deep harborage”

in bed bug treatment, bed bugs

Mark Sheperdigian writes, in a new article for Pest Management Professional, about the difficulties of — and possibilities for — eliminating bed bugs from deep crevices and wall voids.

Eliminating bed bugs holed up in the deep harborage of structural crevices, and voids is problematic, which is a fancy way of saying they are just plain hard to get. Even the most powerful vacuum cannot reliably rip them from their strongholds, and they are blissfully out of the line of fire for most sprayables.

But we have more tools in the shed. Steam has proven to be very effective, but only has an effective range of a centimeter or two and it does not seem to take too many layers of insulation to protect bed bugs from the lethal effects of the steam. The use of cold, as we discussed last issue, has even more challenges in its ability to eliminate bed bugs. In the absence of the perfect and universal solution, the pest management professional (PMP) is left to consider the possible methods available for use and choose the most appropriate for each situation.

The rest of the article does just that.

Bedbugger does not recommend self-treating for bed bugs, for a variety of reasons. However, it does help to know as much as you can about bed bugs as you undergo treatment with a professional.

Although PMP is a trade journal, I find Sheperdigian’s articles readable and enlightening, and I think you will too. You can read the full article here.

My apartment was treated about six times in the last three months for bed bugs and this last time I thought they were all gone… but I spotted a random bug walking across my couch. Could it be a rogue bug or does that mean the infestation is still not under control?

The problem with the “rogue bug” theory is that it is extremely rare to see a bed bug. Even when people have many.

Some people are bitten for many months and see no bed bugs.

So when someone sees one, I kind of assume there are more.

Anyway, if it’s female, you surely have more than one (eggs). Definitely keep getting treatment.

Consider seriously that neighbors are probably infested even if they do not know it. Six treatments, done properly, should be enough. So I suspect either they are not being done properly, or bed bugs are coming from somewhere.

Hi all, I had to (unfortunately) register myself to this site recently. To be honest, I kind of feel better knowing that others are suffering as I am (sorry!) I thought I was the only one and felt so ashamed.

I found out I had BB 2 weeks ago. They came from my mom in law’s place. Her house is severely infested we found out.

I saw one crawling on my shirt sleeve early evening and I immediately called the exterminator. No bites for about 5 days afterwards but on the 6th day, I saw a BB hanging out on my washcloth in the bathroom and we caught 2 more that were in the process of biting my husband while we were sleeping the following night around 3am. I have a collection now in a small jar.

I asked the exterminator how long we have had them by what he found. He said about 3-4 weeks tops. I pray to GOD that my neighbor downstairs doesn’t have them. I did tell my LL what we found but no one else in the dwelling has complained to her.

I haven’t seen any more bugs lately. None of us have new bites. I’m calling the ext. again on Tuesday to do his stuff again but even after that I wont feel too safe.

It’s very sad. This is wrecking our mental state more than the financial state.

Remember: some people do not react to bites, and also, some people do not react right away.

Also, I am surprised the PCO says you have had them only a few weeks based on how many he found; many people have them for much longer and see no bed bugs.

Anyway: lots of support here. I recommend you come to the forum where you will get more responses:
