Hi--
I am new to the group. And to the world of bed bugs--ugh! Investigating possible future treatments (e.g., diatomaceous earth) for after the 30-day guarantee period that my exterminator offers, and I read about Dri-Die elsewhere on this site. Does anyone know if & where this can be purchased? It seems to be somewhat different from diatomaceous earth, right? Anyway, so far, no one (i.e., the chemical supply companies I've called) seems to have heard of it. Can anyone help?

Perhaps, but on this website it is referred to several times as Dri-Die. Check out this FAQ page and you'll see what I mean:
http://bedbugger.com/2007/03/30/faqde/
A further question, I guess: Is drione dust the same thing as Dri-Die? Is it the same thing as diatomecous earth? As Delta Dust? I'm confused. If not, where would I buy drione dust, either online or (preferably) locally? Hardware store? Chemical supply company? Nursery? Or...?

See if they sell it on doityourselfpestcontrol.com they have those products. Delta dust was found by entomologist Michael Potter to be noneffective against bedbugs. See if you can get Tempo and DE.
Good Luck

Based on the writeups on "do my own pest control", TD is silica (as us DE) with pyrethrins in spray formula for cracks and crevices. So Dri One seems similar (concentration may be different), albeit you need an application device. DE/silica with pyrethrins is available under several brand names. Delta dust is a pyrethrin, plus quartz and inert dust.
Green Apple: isn't it also the stuff the hero of last week's New York Press article swears by (and loves to inhale)?

Real name Frank Middleton isn't even a certified tech from what I was told they took it away after the article. He is black listed as far as I know. Delta dust works very well on general insects especially cockroaches but it was found that delta didn't have an effect on them and in some cases they were resistant.

Delta dust, other then possibly inspiring Joe Cocker is actually a" Pyrethroid", and while the liquid formulation of Deltramethrin is not a first choice dust formulations do offer better results when used properly. Tri - Die is a good product but is Restricted in NY. Perhaps one of the biggest issues in the original post is that even after repeated failure they continue to rely on a strictly chemical approach.

Appreciate all the responses to my original post & I am trying to process all this semi-technical information. So apparently a silica (like diatomaceous earth) with pyrethrins is recommended--right? Someone mentioned this being avail. under several brand names, but didn't name any, or recommend any one in particular. By the same token, I assume these would cost more than simple food-grade DE, which I actually found locally for $1.39/lb. (Since it's used with cattle, I assume this DE has no pyrethrins in it.) So now my questions are...would DE *alone* affect the bed bugs? Or should it really be combined with pyrethrins? And as far as I can tell from my research, one can buy pyrethrin in dust/powder form--in which case, how would one mix it with the food-grade DE? I.e., in what proportions? I trust this makes sense, and apologies for being such a know-nothing with so many questions....

Not sure about silica with pyrethroids as "preferable" to food grade DE. The DE FAQ is "silent" on this, but I think there's been arguments pro-con (search forum on "diatect", which is one brand of DE+pyrethroids). If in doubt, I'd go conservative and stick with food grade, applied sparingly (as per the FAQ). Less risk of repellance and/or resistance. The advantage of pyrethroids is quicker knockdown for those bugs that are not resistant, but the silica does the heavy lifting long-term.

And FYI we did refer to it as Dri-Die, it was actually a block of text quoted (I believe) from an article in the Journal of Medical Entomology, where it was referred to as such.

There is or was a product called Dri-Die as well as Tri-Die and they are, were similar in composition.

A check of the NY State and EPA databases does not indicate any current registrations for DRI DIE as a product which as stated above was a mixture of silica gel and pyrethrin powder. There also don't seem to be any veterinary materials either. I remember this product though, it was extremely light. A fair sized box about 2x2x2 was only about 7 lbs.

I'm looking to buy Dri-Die also. Acording to this article http://www.sciencedaily.com/releases/2009/06/090602133555.htm Dri-Die is made from silicon gel and is much safer than diamatacous earth because it isnt sharp but kills the bugs by simply dehydrating them. It'd be great if I could buy a product that incorporated the pharamones described in the above mentioned article but I guess I'll have to wait for someone to manufacture it.

Tri Die. I never heard this thing about silica gel being more or less safe than DE (doesn't mean it's not so, but read the safety instructions for the product).

after looking at the msds for the amorphous silica gel both it and DE appear to be pretty nasty and more of a health risk than I'm willing to take.

Hi -
I am resurrecting this tread because it contains incorrect information and people are still reading it, at least I am.
Tri-Die is not at all like Dri-Die except that both have at least some silica. Other than that, totally different.
Tri-Die has both Pyrethrins and Piperonyl butoxide, Dri-Die has neither. Dri-Die has AMMONIUM FLUOSILICATE, Tri-Die does not.
I wish I could get Dri-Die but it looks like it and everything like it is no longer registered for pesticide use.
Which is too bad, I would have loved to dust the interior wall-space and behind the baseboards, etc. with Dri-Die. It sounds hard to handle but really effective in wall-spaces or any where where it is completely undisturbed. It also sounds to be more effective than amorphous silica by itself, due particularly to its reputed electrostatic properties brought in by the inclusion of the AMMONIUM FLUOSILICATE, at least according to articles I have read on this site and others.
All the pyrethrin formulations strike me as counter-productive. I do not want the bugs to be repelled, I want them to be attracted to to it, to wallow in it until they die. I suppose there might be some advantage to repelling the BB when they are in the apartment next door and you want to discourage them from coming, but my feeling is that the Pyrethrins and Piperonyl butoxide are not repellant enough to be much good, but are repellant enough to reduce the effectiveness of the Silica. Maybe when the pyrethrins break down, the silica will become more useful.
I've broken the URLs because I don't know whether URLs are permitted, but if you re-insert the http colon, they will work so you can verify my claim that Dri-Die is not very similar to Tri-Die.
