Not long ago, I read something somewhere about how you can make bug bait powder that’s reliably fatal, safer than the commercial varieties made with unpronounceable synthetic toxins, and specifically effective against the common and contemptible cockaroach. The recipe was real simple: **half boric acid powder **(the actual roach-death component) and half something else, some powdered food product I think, which was what attracted the loathesome little boogers to eat the stuff.
The problem is, that’s all I 've retained. I can’t even recall if it was on the SDMB or another online forum, or in a book, or the Bug Man column in the SF Chronicle or elsewhere, much less remember what that vital second ingredient is.
My question, then: what IS that second ingredient? Instant pancakes mix? Dried mashed potato flakes? Flour, or confectionary sugar?
Once one has obtained and blended the two ingredients of homebrewed bugdeath powder, what does one do with it? Lay down trails of it along the bases of walls, or leave little mounds of it in the darkest greasiest roachiest spots in one’s area? Burn it like incense while praying to the Mantis Devil? (Okay, I’m sure it’s probably not that last one;))
C’mon, I know there are Dopers who know all about this, and the information would be incredibly useful to have right now. Once again, I throw my need for specific and peculiar information on the mercy, and at the feet, of the largest collection of well-learned people to whom I have access and who don’t mind sharing some of their knowledgeability.
I’ve made roach bait by mixing 1# boric acid with 1 can of sweetened condensed milk. This makes a rather firm dough. Roll it into marble sized of smaller balls and place in corners, behind furniture, and other places where roaches hide and pets can’t get to. (it is non-toxic, but if the dog eats it, the roaches can’t!)
Bumping to add that this is IMO one of the greatest SD columns of all time. You get the strong impression that Mr Adams has fought this battle more than once …
In my experience and the experience of the contractor currently working on our new house, there’s nothing to get rid of bugs like the plaster dust produced by a total gutting of the interior. It may be a little more drastic than you were planning, but it’s effective.
I mixed this stuff up years ago. It eliminated all of my uninvited bug pests for sure, but then I found I had a mouse problem. I know that he (or somebody anyway) claimed it would kill mice too. My mice happily ate this powder without consequence.
DLux, my dad used to make homebrew roach powder with boric acid powder and Nestle’s Quick drink mix. I’m sure Ovaltine and any similar store-brand product would work just fine.
IIRC, the sugar in the Quick was the key. Powdered/crystalline sugar would probably work, too.
Ah … hadn’t read this column in a while. He recommends mixing plain ol’ flour and cocoa powder into the boric acid powder (he calls for borax, actually, but close enough).
I don’t see that in the column … He does add a rat-killer at the end of the original published column. (Which, by the way, looks really nasty. Death by constipation. :eek: ) But I can’t think of any reason that boric acid would be expected to cause a problem for mice, so there you go. (The theories about why it’s fatal to cockroaches all center around its effect on their exoskeletons, which leaves out vertebrates in general as potential victims of this concoction. As Kevbo points out, this is not actually a poison.)
What, you think I’m going to actually read the article again to confirm what I vaguely remember somebody mentioning but had always attributed to him? I must’ve confused the rat poison part with the roach killer part.
Well on the off chance anyone thought this stuff worked as a rodentacide, I have anectotal proof that it doesn’t.
I really want to thank everyone who’s offered their thoughts and advice about the topic. I’ve learned a lot from reading all the replies and right now I’m feeling encouraged to actually whip up a batch of this shit and bring a new weapon into our war with this invading army of uncouth and scuttking arthopods*. You’re swell, top-shelf people in my book just now.
*PS: I hope that people haven’t gotten the wrong idea about our housekeeping hygiene around here from reading multiple posts by me about our problems with egregious insects making free with our dwelling.
The fact is that we live in an older, somewhat deteriorated building; around here, this practically guarentees that situations involving uninvited rodents and bugs will sometimes arise .
FTR, while I’m assuredly not the clean-fiend type, neither do I lay around eating cookies and net-surfing all day while wallering in squalor At least not more than a couple days a week, maybe three, tops.

In some parts of the country, roaches are just a fact of life. My wife and I currently find an average of one dead or live roach around our house every two weeks. As long as we don’t see a population develop, we’re good. Our bigger problem when we bought the place was mice (no this is not the place I used Cecil’s formula. That was ten years ago.)
I read the article too, and I’m pretty sure it recommended a mixture of flour and *dry cement *set out with a pan of water next to it. I’ve also heard of rat bait made the same way except using plaster of paris powder as the lethal ingredient.
Man, I don’t even want to think about those two recipes – while I will go lethal on rodent type intruders as soon as they become obvious, that particular thing just struck me as an abominable, unnecessarily cruel thing to do to other living creatures – yeah, all the way down to rats or mice. At our home sweet hovel, when we have to massacree some mousies, we mostly use classic neckbreakers, and lay down a few sticky-deathtrap-trays if the colonization is so egregious and populous that we really have to (I don’t like using gluetraps since they, too, strike me as being awfully inhumane – especially compared to the swift surprising SNAP! of the killbar across the beasty’s ratty little neck or cranium – but sometimes our deeds’ thrust can only be as needs must) .
That was certainly my thought when I read that suggestion. I don’t mind dehydrating roaches over the course of days or weeks; but as troublesome and filthy as rats and mice are, I don’t like the thought of torturing them to death.
OTOH, my house is efficiently kept free of rodents by my horde of cats, who probably don’t concern themselves too much with how humanely they dispatch them. I just call that the ‘circle of life’ and try not to think about it too much.
My experiece when we were overrun by roaches once in an apartment we lived in years ago:
I pretty much covered the kitchen with Borax (10,000 Mule Team). All along the baseboards, cabinates, frig, behind the fridge, etc. Then I mixed up some Borax and powered cocoa mix and left a couple of piles and/or paper cups with that mix to attract them.
couple of other hints:
if you find a dead one in or near the borax leave him there. Other roaches will come along to eat the dead and go through the borax as well.
obviously you want to not leave food out, but also don’t leave any standing water. No water in the sink, or dishpan, etc. Roaches need water also.
It could still take a few weeks to really get rid of them (in fact you never really get rid of all them), but this worked for me. After, I just made sure to leave some borax in their favorite places (under the sink, fridge, etc.)
