Alma's Roach Bait is DUY
16 oz Boric Acid
1/2 cup Finely Chopped Onions
1/2 cup Sugar
1 cup Flour
Lard to hold it all together
Add Water to the consistency of clay
Boric acid 99% is usually available at the True Value Hardware on Lomas, next to Sprouts. It's marketed as "Roach Killer".
Boric acid is safe for most non-insect lifeforms, including kids, dogs, and kitties, as long as it is not consumed in mass quantities.
Coconut oil is a good substitute for lard.
I crumble it up and spread/place it, judiciously, in strategic locations: the back of under sinks, near possible water sources like hose bibs, crawl spaces, etc.
It is not as toxic as commercial organophosphate poisons and requires time and diligence. I was able to downsize my cockroach population by 95% over 1 year.
If you are seeking more immediate gratification, I suggest finding a so-called "eco-friendly" pest control service for a single application of their poison, and distribute Alma's Roach Bait to control the survivors.
Keep in mind that our urban roadrunners have adapted to prey on our urban cockroaches, now that we've lost almost all of our lizard (Blue Whiptail) population over the past 40 years.
