Boric Acid Roach and Silverfish Killer Powder w/Lure for Insects (16oz)

I use this product in conjunction with other products. It is mixed with Borax, diatomaceous start, powdered clove, and carpet flea remover. It works very well. I have seen a reduction in roaches. It can be easily rinsed off. I like the value that I received and the price that I paid. It has no bad smell and is odorless. The cone shape cover was hard to get off. But that is the case with all of these security covers. It's not like you're taking off the cover of a golden mustard container. A lot more security. It was easy to apply by itself. There was no leaking. It is easy to store based on its size.

Used a bunch of this stuff around the outside perimeter of my home because my next door neighbor's home is/was ground zero from where offending "insects" were coming from. Not long after my application, it seems that I not only stopped the invasion onto my property, I apparently also neutralized the active "insects" at the neighbor's property. Plain & simple, this stuff works as good today as 30 years ago..

This product does work. I git rid if the entire population 99.9 in three weeks of regular use. The rest 1% am sure I will get rid of in the coming weeks. Just simply spreading the power on floor or in corners may not work. But I had to do a bit more from my side,rather than just simply dispersing or spreading the powder, I spread the powder in small "trays" (the lid of the food containers we get from restaurant) . Then I prepared a "bait" . I took some left over food,cockroach's favorite food (a little fried rice, potato french fries, oily fried fish and sugar) and mixed it with the powder. Then I placed a little bait in the mid of the each trays . Placing it mid made sure in order to eat they had to pass through the powder around it. I placed the trays in potential locations (kitchen, bathrooms ,dining rooms) during the night. I made sure I did clean the area and floor before I placed the tray. This will make sure the only available food is the one in the tray in those locations. The bait(good oily food) and powder will easily attract the german cockroachs as the lights go down Every night they came and ate the bait as well as powder. They passed through the powder and carried home the powder and food along with it. Next few mornings I just harvested 100s dead cockroach from tray and around the floor. Every night I gave them fresh "bait" (basically oily food with sugar mixed with PF Harris powder) and placed it in mid of tray. They should be able to get into tray and get out easily. Make sure the tray is NOT having TALl smooth surface . Better is paper tray (make one if you can ) . A pizza box is a good one for this purpose. Some may have went back to the nest and died. They took the powder and food carried along with them to nest. I read and researched that The female cockroach (are usually back in nest with egg) and with babies . They ate the powder on the body of these carrier cockroachs coming back and females and babies die. Once they all start dieing and stop getting the food they start eating the dead ones ( poisoned and having the powder on their bodies) and the rest remaining aldo die. It will be a chain reaction and the entire population is eliminated. The point here is you need to let the cockroach go back to the nest after it visited your tray. They will die eventually and will carry the bait and powder back home yk kill the others. Never kill (intentionally) the contaminated carrier cockroachs,let them go back to nest. It takes more than 72 hours to see a noticeable impact so don't get discouraged or disappointed. It takes time and very slow but effective and eliminates it from the roots. It worked for me .I have reduced it to 99.9 % for sure in last three I zm going to continue this for next one month until I achieve 100% success.

WORKS GREAT!!! Nice size bottle in appearance! Just wish my bottle didn’t arrive HALF full! You just don’t get good quality products anymore without somebody trying to get over!!! I purchased this bottle for the nozzle. Once empty I refill it w/the tablets this same brand sells only I crush them up in a ziploc bag before transfer. Wayyyy more potent & haven’t had an issue since!!! Roaches eliminated! Line those baseboards after cleaning them & you’re good to go! Make sure it doesn’t get wet or it’s useless! Hope this helps!

*Note* I don't know how common this is, but the cap on the item I ordered was loose, so the Amazon box was full of white powder that was covering my other purchases when it arrived. So maybe don't order this item along with other products that you don't want to get covered with boric acid while in transit. Also, it took me a while to figure this out, but you have to cut off the tip of the applicator with scissors. The entire lid can screw off, and there's a replaceable cap, but there's no real way for the powder to get out unless/until you manually cut off the applicator tip. Anyway, I love this stuff. My previous method for dealing with roaches had been to chase after them with a heavy-duty flyswatter. The down sides to this are that, A) I, as a germophobe, hate having to clean bug guts off the flyswatter afterward, B) my aim isn't the best, so half the time I'd miss and the dang roach would escape, and C) for every individual roach you kill, there are who knows how many still hiding out of sight in the walls or whatever. Using boric acid is better because, not only can you use it proactively and passively (you can sprinkle it around your home and let it do its work regardless of whether you're paying attention or not), but I feel that it's a lot easier to clean up. I don't have to stress about cleaning an instrument and then cleaning everything the instrument and the water touched; all I have to do is just my regular vacuuming routine, then re-apply boric acid if necessary. Also, you don't have to have good aim if you see a roach, you just squirt the bottle in the right direction and you'll probably get a decent amount of power on the insect. From what I understand, the way the boric acid works is that if/when a roach walks through it, it sticks to their feet; then when they clean their feet, they ingest the poison, which eventually kills them. I also had to re-train myself to just toss powder on them and then let them run off - not only does that save me the time and stress of hunting, but with luck, it'll also kill more roaches behind the scenes when they interact with the contaminated one. In a recent incident, I encountered a roach and threw boric acid on it; it freaked out and ran around the living room, but couldn't find a way out (I practically have no furniture and I plug up all the holes I find). I noticed that its gait was starting to get irregular after a minute, so maybe the powder was affecting it without it even having to eat it. The roach eventually stumbled into a spider's web and couldn't get out; by the time I finally had time to dispose of it, it was very dead - not sure if that was because of the powder or the spider, but either way, good riddance. Note that a wide, thin layer that bugs can't help walking through is a lot better than a thick clump they can easily avoid. I'm also under the impression that boric acid loses its effectiveness if it gets wet; if nothing else, powder that gets wet will clump together and will no longer stick to the bugs' feet if they walk through it. Also, boric acid is probably not a good option for households with members, such as young children or pets, who might be tempted to eat the powder. But if you don't have to worry about vulnerable housemates, boric acid is great and I recommend it to help with roach problems. (I haven't seen it affect any other kinds of bugs, though.)

Wonderful product it really works. The reason why I gave it a three out of five is when I open the bottle less than half of the powder was in there. 1/4 of the powder was in the bottle.

Used bottle having half filled quantity, without a tip, not useful
