I found the original post from Lou Ann in 2015, sharing her cousin’s recipe. Here is the post that includes how you use the bait.

Alma’s Roach Bait

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

Mix all ingredients. Chill. Make small, slightly flattened balls.

Serve on a dish; this concoction is greasy when it warms up and may stain fabrics, flooring, etc.

Serves thousands.  Recipe may be reduced proportionately.

Refrigerate until ready to use.

How do you apply or distribute the bait, Sam?

Here's a roach bait recipe that pretty much cleared up my massive roach problem, near Hyder Park, after a coupla years. 1st year saw a 75% decrease.
It's, basically, inert/non-toxic to humans and other vertebrates.
The active ingredient, 99% Boric Acid, is sold as "roach killer" at most hardware stores.
Instead of lard, I use coconut oil.

Hello All:  I am wondering if anyone else has been experiencing the appearance of cockroaches during the past few weeks.  I have notice that each morning I find 5 or 6 of the buggers mostly dead on the floors.  It seems a little early to me for this to be happening and I am wondering if anyone else is dealing with the same thing.  Located near Lomas and Solano.  Thanks.
