HARRIS 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.

It helps draw insects in, and the formula stays active for a long time.

Did not seem to work for me. I have cats so I couldn't just leave it out in the open cause they might eat it and get sick. I tried to mix it with peanut butter to see if that would help, but not sure if I did something wrong? I will try again and it if ever works I will give this a higher review.

We used to have terribe infestations of "sugar ants". In a search for a solution I learned about Boric Acid. To start with, despite some CYA warning labels it is not harmful to humans. You may even find that dilute solutions are sometimes prescribed for applying to infants. I've never been able to find out why it kills roaches and ants but with certainty it does. One crazy sounding explanation I ran across thought it was because the boric acid formed tiny crystals that cut up the insides of the insects but that is too hard to digest as a sensible answer. Anyway, there is considerable erroneous information about how to use this stuff to kill sugar ants but here is the sure fire approach I've worked out through experience. What you are striving for is a sugary solution the contains boric acid. Boric acid is not very soluble. If you start with a sugar solution then try to add boric acid you are operating in the blind because it will be frustrating trying to dissolve the Boric acid. My approach is to add as much boric acid as can be dissolved to a quantity of boiling water, say a quart. Add a tablespoon of boric acid at a time. You will find it doesn't want to dissolve easily so just add a table spoon or less at a time until you can see no more will dissolve. While the water is still hot strain it so the excess is separated. This should now be what will turn out to be a supersaturated solution when it cools. Adding a few crystals to the cooled solution should cause the excess amount that is dissolved to crystalize out leaving you with a fully saturated solution to work with. The original formulation I read about prescribed dissolving as much sugar as the solution would absorb until you have a syrup that can then be left in appropriate containers to attract the ants. I have found however that using honey instead of sugar works best of all. Sugar ants are crazy for honey so I add a quantity of honey to the saturated solution and then it is time to rock. This is the part of the operation that always reminds me of the story of Moses and the rock. You have to have faith that the solution you leave for the ants will work. I usual resort to using the solution when ants are crawling all over whatever space is involved. Once they discover the glory hole you've put out for them, seemingly every ant within a mile is invited to the party. If you think you had some ants before you started the party you will soon find out it was nothing compared to the mob that suddenly appears. For at least a day or more this ant Woodstock Festival will rage and you will be asking what terrible folly you brought upon yourself. Then a morning or two later when you come to check on how things are going, there will be no ants in sight. It will be like a miracle has occurred. They will be gone, gone, gone. It is truly bizarre. I have used this remedy many times and there are never any dead ants laying about. All I can figure is that they must get terrible tummy aches and rush home to die quietly in bed. Some people say they carry the poison back to their nests and take down the whole tribe with them but I'm not certain that is true. Sugar ants do not have central governments. Rather, somewhere there is a nest that becomes the node of a network of nests each of which becomes the node for more nests, each node having its own queen or queens. You may kill off an entire node and it will take a long time for a forager from another node to rediscover the path to your kitchen again (because all the ones who did know are now in their graves) but in time a new explorer will show up but it can take months before that happens. I still have things to learn because sometimes they appear to not be attracted to the sugar. I've been told some of the little ants prefer protein substances and tend to eschew sugar but I'm not convinced that explains things.

THIS REVIEW IS REALLY MORE SO FOR THE ADVION COCKROACH GEL BAIT (but I also bought Harris Famous Roach Tablets at the same time) ..... THE AMAZON LINK THAT I BOUGHT IT FROM WON’T ALLOW ME TO LEAVE THIS REVIEW FOR SOME REASON..... ALTHOUGH IT MIGHT BE BECAUSE IT CURRENTLY HAS OVER 13,000 REVIEWS AT AN AVERAGE OF 4.5 STARS!!!!!!! I'd like to begin with stating these things could come from anywhere. My house is clean, we sweep, wash floors, bleach our bathroom but it happens. My landlord provided a stove from another unit ...... and it came with roaches. About 3-4 weeks after that I noticed the problem. I was using Raid in a can but that only works if you happen to them, doesn't do much for the colony inside the cracks and crevices of a wall or under a kitchen cabinet. The only thing they got into was the sugar and flour. I've since learned my lesson and keep that stuff in a plastic container. I used this product in conjunction w/ "Advion Cockroach Gel Bait, 4-syringes 1.06 oz" . I had an infestation although I'm not sure how big or bad it really was because I haven't woken up to a RAGING sea of the dead as other consumers have. But I assure you it was an issue for us ...... I'd wake up at night or around 5 am and find a slew of them by the dog's water bowl and on the counters and in the sink. Now while I am very clean I do leave a few dishes in the sink from the night before and wash them in the morning when I wake up before I go to work but I don't leave FOOD behind, just rinsed out dishes. But now what I can say is this ..... might not see the dead but I don't see the slew that I used to see! I do a find a few walking dead in search of something to save them from the dehydrating effect of the boric acid (gets in between the exoskeleton and body; dries them out almost instantly). Or they could have been dying from the Advion, they eat it, it blows their stomach up (if you step on them they make a light popping sound). The Advion is great because it kills them, they die and then their fellow roach eats them or eats their feces ... very infectious among a colony and VERY effective. So with said ..... this stuff works. I bought both items Thursday 6/21/18 afternoon, arrived Saturday morning 6/23/18 via U.S. Postal service. I applied both items around my kitchen Saturday night around 9 pm. I used the red straw that comes with the boric acid; sprinkling a think line about 6-8 inches long under each of my two 6ft long floor radiators. I also put it on both sides of my fridge and stove. Also a small circle of it under sink cabinet and in the lazy Susan lower cabinet. On Sunday morning around 6am (I have 2 small dogs so get to the floor to clean up anything found dead so they don't sniff or eat it) .... found a number of dead and walking dead. But more importantly I found all of the Advion poison I put out the night before was COMPLETELY consumed. I put the size of a pea in water bottle caps (10 total) around the kitchen (under radiators, counter tops, under sink) and in the electrical sockets. If you can stomach it, sweep them up into a pile under the radiator .... the living eat their dead so the poison keeps spreading. I writing this review on 6/27/18 @ 8:35 am ..... I woke up to NOT one dead or walking dead thing this morning. Now you have to remember that you may have killed the adults but the young will soon hatch or grow up enough that it's time for them to search for food and water .....so keep applying both items every night even if you don't see dead things in the morning. So 4 mornings have passed, and I have gone from finding many to none. The boric acid is still on the floor and admittingly it doesn't look like they've been eating it but I know it worked because I saw them walking dead to find water. But the Advion is still be nibbled on. They don't completely eat it all up like they first did but they nibble and so that means there are fewer of them and its slowly killing the rest of the colony. I will add an update in a couple of weeks. Things to remember ..... I changed out the old poison every night, I wiped down my counters w/ a mix of water and bleach in a dollar store spray bottle EVERY morning when I woke up, when I came home from work around 6 pm because they crawl on the counters at night and while you're not home in search of a reprieve from death while shedding their layers, I made sure to apply where the dogs can't get to the Advion (it looks like peanut butter and my dog tried more than once to eat it), Also sweep up the dead in a pile under a radiator, they eat the dead. I haven't used in the bathroom because I've never seen one in the bathroom but I will begin that tonight now that I'm thinking about it while I write this review. So yeah ......buy Harris Famous boric acid and Advion Cockroach Gel Bait (link below) because they work. Advion Cockroach Gel Bait is definitely a 5 STAR purchase!!!! https://www.amazon.com/dp/B002Y2GNVM/ref=cm_cr_ryp_prd_ttl_sol_1

Dont have kids or pets and moved into an older cheaper apartment building. Maintenance super attentive but it roaches were back a week ago bug maintenance sprayed. So I waited over a month before even buying furniture and boric acid the lining of all the walls and crevices. After about 2 applications and 4 weeks later, in addition of using the roach bait gel (that is brown and looks like a roach itself when dried), i used silicon caulk to start plugging up every little hole i saw roaches either coming out of or hiding in. Then at about 6 weeks I swept it all up and washed the floors, only leaving the gel bait in the bathroom flooring and around the toilet. Then at about 7 weeks in I was finally going more than a week of being bug free. Then about 3 weeks later. The temps dropped and I started seeing this giant roaches. I swear I thought they were coming out of the vents bc I plugged up every hole possible...except for the utility closet and laundry room bc of the cramp space. maneuverability, and all those tubing, Cables, cords I didnt know what was safe to patch or even touch. Sadly there gap for the laundry door was just way too big to cover. I got these under the door bumpers that filled the gap under the door. And put it under the 3 doors I thought they were coming out of, and its been at least 2 weeks and I havent seen ANY bugs. (2 closet doors i put bumpers on, I suspected was the entry point for the random wasps i kept seeing).
