Useless for bigheaded ants
937255
100% Useless for bigheaded ants even though the label specifically lists this product to be used for bigheaded ants. I tried it on two different properties over the course of a year and never once could get the ants interested in taking the bait. Each time, days later the bait was still there with the ants walking right by it.

I would recommend Advance 375a for bigheaded ants instead. The bait would get taken away by the ants within hours and with just a few treatments they were gone forever.

Ants don't care about this stuff it was a complete waste of money. This does not work on Odorous ants. The design of it also leaves much to be desired it spills out way too easily. I was also dumb enough to get two boxes of these so I have a box of this useless junk. Going to try Orthro home parameter spray next hopefully that will have better results but I have seen no ants being attracted to the liquid inside of this container and that includes other species of household ants. They all ignore it entirely. The most they'd done is taste it and then move on. What ants do these things even work with? I've yet to find a trap that did what it said. All this does is create a sticky mess for you to clean off your hands and floor when it accidentally spills out.

Useless. Ants approach poison and run away without touching.  I bought this exact product 2 years ago and it was the best ever. Advion needs to fix this before I purchase again.

In the summer ants come in looking for water. I was hoping these would help, but they don't seem to prevent the influx. Oh well, maybe they are repelling some unknown something.

My mom bought several packages of these for a rental property swarming with ants. Mom has respiratory issues so we had to be careful about spraying or putting out dust materials.

The ants walked on these, around them and most ignored them. No change whatsoever. I purchased some Terro traps from Amazon and the ants almost attacked them. It was amazing to watch.

MaxAttrax was totally worthless for the ants we encountered.
Terro ant baits worked like magic.

I put several of these out on a bathroom counter where black ants were suddenly making a BIG appearance---after 2 days, and checking in there many, many times/day, I have yet to see ANY of the ants go anywhere near them !! They simply sniff at it and wander away, or crawl over it enroute to somewhere else.  Total failure---save your money!

Sorry to report that we still have ants.  We can't see any improvement, even after using them for more than two weeks..  We are thinking about returning them.

I got these a week ago because of the reviews and information provided. Because it's summer the heat has created a little ant problem. Plugged all of them in. After 3 days no results. After one week ants are crawling over the boxes themselves.   No results whatsoever

Only used once to kill the ants near my chicken coop. Seems it worked fine. But I hate the spray head. It only goes in a straight line with no actual spray range so you have to aim pretty well at the ants. Wasted a lot during the first use because I  had to spray in a big affected range by the straight line of liquid. Why can they use the nice spray head like the ones with Windex? Will not buy this product again just because of that.

The ants did not seem to be attracted to the bait.  Maybe 20 got into the trap and drowned. The worst part was that one of them leaked onto the counter and was difficult to clean up. If you accidentally tip or turn the trap over, the bait runs right out.  I have used the liquid drops for years with excellent results but the trap seemed preferable since it (supposedly) enclosed the bait. Since I have a cat that sometimes jumps up on the counter to see what she can get into, I didn't want her to lap up the poison.

I've been deceiving my husband about ant bait traps, and in my opinion it's because the makers of these products are deceiving the public - they don't work!  At least they have never worked for us.
Sure the IDEA is great, of killing not just the ants you see, but infecting the whole colony.  So whenever we have an ant problem, my husband rushes to by bait traps.  He will not consider any other approach.
We get an ant invasion about every 3 years on the average.  It's not that we failed to kill them and they come back, because it's been different types of ants.  Last time it was little tiny black ones in the kitchen.  This month it's carpenter ants in the upstairs bathroom.
Note these are NOT places where I want to have to wait days and weeks to get rid of ants.  Not that the bait traps work even after weeks of trying.  Meanwhile we are talking about ants crawling on counters where I need to prepare food, lay my toothbrush, etc.
So, what happens every time is that after a few weeks of using Terro with no reduction in the number of ants, I can't take it anymore and I just deal with the ants myself.
First I remove all items from the area, contents from cabinets. etc., and wipe them all down with soap & water.
Then I scrub all surfaces with disinfectant.
Then I spray all crevices, floorboards, etc. with plain old Raid Ant spray.
Then I wait an hour or so with windows open for ventilation.
Then I wipe all counters again so there will be no chemical residue from the bug spray.
Then I put everything back.
Every time I go through this process, the ants disappear for the next few years.  I mean they disappear THAT DAY, no matter how many weeks the bait traps have been out.  And again, during those weeks there was never any reduction of ants.  And as I said, it's years till we see ants again, and not even the same ones.
I have not told my husband because he can be very by the book about some things, and he is so sure that it is essential to rely on bait traps so that we will 'kill the colony'.  In fact this morning he even said I should not wipe the bathroom counter for the next couple weeks because he does not want to interfere with the operation of the bait traps!  Yuck, it's bad enough there are ants on our counter, and now there's a chemical poison there as well, plus I am not supposed to clean my bathroom counter for a while?
So today when he was out, I did my usual own process, and of course this evening the ants are gone.  I did at least cop to having cleaned the area (since it was obvious I had cleaned in there), but still have not told him I used Raid (windows are open so the smell was gone), because he'd say that would keep the ants from coming to take the bait.
Maybe someday I will come clean the rest of the way and tell him we really have to thank Raid, not Terro, so that he will stop giving Terro our money for nothing.
Meanwhile, I can't help wondering if some of the positive reviews here are from other people who don't know that their spouses or roommates actually got rid of the ants using Raid, and let Terro take the credit.

I have used everything I could find to combat the yearly ant problem, nothing worked.  I put one of these out a few days ago expecting to see the ants just walk by it.  I had the biggest ant party yesterday! I was amazed to see thousands of ants eating this stuff. After about 4 hours of continuous eating, most went back to their home in my window sill, while some ate so much they just died at the buffet. This morning I waited for them to show up at their regularly scheduled time...only 1 ant was walking around. My husband said he was the investigator for the mass murder yesterday. It has now been 2 hours and the only ant is still walking around and NOT eating the bait. For once in 20 years, my husband might be right.

Do you like ants? You will have them if you used this device. I don't know what it is about this thing that they like, but they cover the heating element at night. I woke up to hundreds, if not thousands of ants on it. I checked to make sure there was nothing else that attracted them and there wasn't. I won't be buying Vicks again.

these don't seem to work at all. left them outside in the yard and ants still roam around - they avoid these traps.. DONT BUY!

We use it mostly for flies.  You have to be right over the fly to get it.  It is pretty useless.  Hardly any suction power to it at all.  It might work alright on ants.  Haven't tried that yet.  I would not recommend this item.

Have small ant problem. Big problem with small ants. Did nothing. No ants went in. Maybe it only kills big ants?

A couple weeks ago little black ants invaded my living room, rummaging through my carpet, swarming my upholstery, and marching by the hundreds along the wall.  I'm sure it had nothing to do with my 3yo's half-eaten cookie under the tv console, the crumbs from the other half undoubtedly splashed all over the sofa.  A trip to home Depot yielded&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Combat-ant-traps/dp/B000VA90FU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Combat ant traps</a>, which proved a joke since ants simply went around it completely disinterested.

I followed their industrious little parade outside along the foundation, so I knew where to hit them there when I tried the Terro outdoor ant baits.  The traps set up easily and come with a set of stakes each to anchor them into the earth.  Within a day the steady stream of hundreds was down to a few dozen.  By day two, no ants.  Victory!

Now the instructions tell you to push the liquid capsule down and the picture shows it filling a reservoir that ants enter, like some sort of deadly grotto.  Since the box had six traps and our small townhome only fit five across the outside, I decided (explicitly against the instructions on the box) to put the sixth inside.  What happens when you puncture and leave the trap inside is you get a very large, very sticky puddle.  So don't do that.  I checked the ones outside and it looks like they also leached poisonous gel, so it appears the trap is designed to use some spill seepage to attract ants from below.

Terro basically uses&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Borax/dp/B000R4LONQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Borax</a>&nbsp;as a poison with a sweet sugar-gel to attract the ants, same as grandma's ant-infestation remedy.  The housing of the Outdoor Ant Bait (mostly) shelters it from rain, which makes it last much longer than just trying to spray or put down gel drops directly outside.  The convenience of punch, drop, and forget about it is worth the price - they're very effective.
