What do if they are in power outlets?

I had a 70 yr old house that was do infested after tenants were evicted that roaches covered the ceiling and were falling off. Obviously they were having a blast INSIDE the walls too. Since thete were several holes in the eall and missing outlet covers i just spooned it into all of them before patching and covering them. Used aspray for the ceiling one time when i started repairs. Left this at all the baseboards after everything else was cleaned. By the time i moved in 6 weeks later, NOT A SINGLE LIVE roach left!! I left the powder in place and maybe once a year if i happen to think of it i would puff a fine layer on it again. In over 10 years that i was there i never sae another roach or evidence of any. Rarely saw a stray ant. I swear by boric acid product over ANYTHING I've ever used, including exterminator services

Is there a trick to getting the powder out? No matter how much I shake or squeeze nothing comes out of the tip.

Hello, Thank you for your question and I apologize for this inconvenience. Using scissors, carefully cut the very top of the tip. This will create a small opening that allows the powder to be puffed out. Best, John

Is the bottle suppose to be halfway full when it arrives ?

The product bottle contains 16oz of product, typically, in my experience the bottle does not arrive completely full. I believe the empty “air space” is helpful in propelling product to desired area.

Does this kill centipedes

when mixed with a small amount of meat...I find it might kill anything.
