Zap-A-Roach 3 Pk, Boric Acid Roach & Ant Killer NET Wt. 5 Oz. (142 GMS) Each

This boric acid is easy to use and very cost effective. It's supposed to be for ants and roaches, but we found it works on termites ( or carpenter ants?) too. Takes about 3 days to kill all those pesky termites. A lot cheaper than the termite guy's $2k bid, and likely worked just as well.

My living quarters are roach free. But my yard and my house's dirt-floored utility area--attached to the house--are not. Until the reasons for that are handled, I need to keep roaches out of the house's living area. A line of (unscented) boric acid can do that. (Unscented because if you use scented roach killers, some roaches who can smell them will avoid them and breed more roaches.) I place a line of boric acid across doorways from outside to inside. Roaches who touch that line will die at some point shortly after they cross. It is hard to get the fine boric acid powder evenly out of the bottle. I unscrew the lid, get a pile out, and then spread it out with a new wooden craft stick, which I throw away far from where any child can get it. This method of roach control is NOT safe if you have small children or pets.

Works like a charm! My used this when i was just a boy to get rid of roaches. It takes a week or two to see the full effects, but you will truly appreciate the results. You just sprinkle a light dusting in the places where you see the roaches the most, and let the powder do the rest. They walk through it and take the poison back to their hive and infect the others. Now i just sprinkle a little around twice a month as a preventive measure to keep the roaches from coming back since i killed off all the ones that were within my apartment.

Powder works fine, just constant clogging because of tip. Have used other brands for decades, every once in a while you get the bottles that clog to easy. Powder works great in dry environments. You must remember it's not poison (so safe for pets and people), it works in a dry environment by using static cling to attach to the bugs hard shell. Microscopically the crystalline structure is like broken glass and and cuts through their shell and they dry out. So if your where it's humid, or use in wet area it won't work...

I am very unhappy with this product. The smaller than usual bottles were less than half full. Very poor value for the money. Frankly, it is a ripoff! Do not order this product!

I understand that powder "settles" but this is ridiculous. Even if the weight would be 5 oz. advertised, who needs extra bottles? I've used the product for years and it is effective for outdoor ant colonies, but one full bottle would be better.

Love this product

Set this out as bait and laid waste to a colony of ants. They were benign, harmless, even industrious - their only sin was existing in the same sphere as me. Within a day they were feasting on the sugar water and acid mixture I laid out for them. Within 2 days they were gone. Yeh, this is a powerful tool. But beware the toll it may take on your conscience, laying such a humble and hardworking expression of life to absolute ruin.
