Cockroaches won't survive this killer recipe made with deadly Boric acid. The poison is natural and has a low toxicity to humans, but kills roaches when ingested.
In this "Roach-free recipe," you'll make a tasty (to roaches) poisonous dough that can be pressed into useful shapes and placed in areas roaches can find it.
- ½ Cup Sugar
- ½ Cup Flour
- ½ Cup Crisco Shortening
- ½ Cup Boric Acid Powder
- Mixing bowl and spoon
- Latex gloves
- Work area separate from where food is prepared
- Old jar lids or wax paper squares to keep greasy cookies off your floors and shelves.
- Cover your work area and put on latex gloves. While contact with small amounts of boric acid is generally considered safe for humans, it could irritate your skin.
- Combine ingredients and mix into a thick dough.
- Press into jar lids or roll into shapes and place on wax paper squares, then wipe down your work area and wash your tools.
- Place on floor areas well away from pets and children: Under the stove, under and behind the fridge, under sinks and cabinets.
- Place in elevated areas where kids can't reach: Pantry shelves, the tops of cabinets, and the top of the fridge.
- Scout out other areas of cockroach signs or infestation, including corners and gaps or cracks in walls.
- Check locations every couple of weeks, and replace when the dough dries out.
- Use remaining boric acid as a light dust near areas of infestation. Roaches will die from walking through it, too.
