How To Make Boric Acid Roach Baits, Even If You’re Terrible In The Kitchen

Roaches are protein eaters. They go crazy for the oddest stuff. You’ve heard how they go crazy for the glue that’s used for putting up wallpaper, right? I mean they literally eat the house. That’s because that glue contains a significant amount of protein. To be fair though, once that glue dries it’s useless to them unless it’s the right conditions that soften it.

A lot of article you’ll find on the net will say that roaches go for sweet stuff. News flash, they’ve evolved to avoid it. Roaches now avoid sugary baits. At least the ones in my kitchen do.

So. Here’s a recipe on how to make roach baits with boric acid.

First you’ll need to get a cheap bowl. Either from the dollar store or some second hand store. Once you put the boric acid in that bowl it can never be used for anything else other than making the bait. It can’t be and shouldn’t be used for anything for human, or animal consumption. So please don’t use it to feed kitty or fido when you’re done. Put it away for when you make another batch and mark it so nobody else mistakenly uses it. While boric acid has less toxicity than table salt, it’s still not table salt.

We’ll do the fun part first. Cooking bacon! We need the grease from cooking it for the bait. Cockroaches go crazy for it. Not much instructions needed here. Cook it up, drain the grease to another container. One package of bacon should be enough.

Now that you have the bacon drippings you need:

  • 1 Cup Borax
  • 1/2 Cup Flour (doesn’t matter if it’s white or wheat)
  • 1/8 Cup Powdered Sugar (optional)
  • 1/8 Cup Bacon Drippings (Bacon Grease)

Now just combine all four of those ingredients in the bowl and add water till it makes a soft dough. Not too much, you don’t want it super wet, but you don’t want it dry either. Once you have it like a slightly wet playdough consistency you can either form balls with it or you can use some tinfoil and a soda bottle cap to form pills. You might want to wear gloves while handling the bait.

Place the bait in areas where you’ve seen roaches. Once every two or three days, check on them and spray them with water to keep them moist so the roaches smell them. Just a word to to the wise. This is not an instant kill solution. Roaches have to ingest it. Once ingested it’ll take anywhere from 24 to 72 hours kill it. Now, go get em.
