You Are Using Boric Acid Wrong (And It's Making Roaches Laugh)

I see this under every kitchen sink I inspect. A massive white pile of Boric Acid powder. It looks like a snowdrift in the corner.

And right next to it? A live roach.

Here is the mistake: Roaches aren't stupid. They won't walk through a mountain of powder. It gets in their eyes and antennae. They just walk around it.

Less is More

Boric Acid works by sticking to the roach's legs like static electricity. When the roach grooms itself later, it eats the powder and dies.

To make this happen, the layer of dust needs to be almost invisible.

The Test: If you can see a white pile, you used too much. It should look like a faint layer of dust on a bookshelf.

The "Puffer" Technique

Don't use a spoon. Buy a cheap plastic bellows duster (or use the bottle tip).

Shoot a tiny puff of dust under the fridge, behind the stove, and into the cracks where the pipes enter the wall. You want to coat the surfaces where they hide, not the open floor.

Is it safe?

It's safer than Raid, but it's not harmless. It's about as toxic as table salt.

Keep it away from dog noses and baby hands. If you puff it deep into the voids behind cabinets (where it belongs), nobody should be able to touch it anyway.
