Trying to get rid of ants

Got this or a ant solution.  Supposedly mixing this with boric acid and leaving it out will  eliminate ants. will update on progress.

These worked great at first at keeping ants out of the food. However, now the ants are getting into the food and I don't know how! The dishes are up off the ground due to the stand. They are easy to clean however.

This is a good product.  Really works to get rid of carpenter ants and others as well.

I probably would have moved out of my house if not for these things. I hate those little tiny sugar ants- they pop up near our doors a few times a year, and grosses me out to no end. But by placing one of these near their entry point, they were all gone within a few days.
You just snip the bottom and place the trap in a place where they seem to be coming into your home- they will swarm on it (it's gross), but then they bring the poison back to their nest and they all die! On the first day there were hundreds, but by day 3 there were only 1-2. Then there were none. :)
One warning- keep it away from pets. if we used it outside, we put a rock on top to keep it from getting moved or eaten by bigger creatures. If we use it inside, we cover it with a small cardboard box (with some weight on top) and cut a little "door" so the ants can get in, but pets can't.

We bought these from Home Depot when they still carried this product.  Earlier this year we set out the stakes in our bathroom where they sat for months with no effect. The black ants seemed to ignore the stakes.  Then I called the manufacturer and was told I needed to wipe down the floor or surrounding surfaces where ants were seen e.g. counter tops, as well as the stakes with full strength white vinegar to eliminate the ant trails.  Then repeat with the vinegar every 2 days.  White vinegar is only recommended on non porous surfaces otherwise the acid may cause damage.  By 1 week the ants were gone.  Since the product contains arsenic, we were careful to wipe the stakes last to avoid contaminating any surfaces with insecticide.  According to the representative these never expire.  So if you have some old stakes they should still be effective.  We took off one star for having to require this extra cleaning step and for not including these instructions in the packaging.

I THINK it works.  Ants seems to have left, but I'm too afraid to leave anything on the counter to test it.  Go by other reviews than mine,,,

The ants seem to love it but they never stop coming. I can't tell if the product is not killing the colonies or if there are just way too many ants where I live.

Terro works great, no matter where the ants are, but if you are looking to solve a kitchen problem and don't want to use spray, or ineffective traps, this is the stuff to use.

Put some drops down, watch the ants gather at the drops, refresh drops as needed and in a week to 10 days, no more ants. No smell, no residue, no danger to food.

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.

These bait traps worked great in getting rid of my mom's ant problem.  She was being overrun with ants in her kitchen.  We used spray and Terro but this was the only thing that worked.  My purchase arrived sooner than expected.

I really didn't see a noticeable difference. I do have a problem with ants and they were still present after spraying this all over my backyard. I am sure it works but not for the huge problem I have with ants.

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.

These work great and will take care of the ants. I have used them inside and on the porch. Got rid of my ant problem.

These work very well. About once or twice a year the ants decide they need to come in my bathroom. I leave one of these on the counter until I see no more ants (about a week) and then throw it away.

The south is overrun with ants.  You can easily use 10 to 25 pounds an acre.  I used this late in the season.  You have to remember to sprinkle it late in the evening when most of the ants are back in the nest.  Always look for their escape tunnel & smaller nest & get it too.  You have to moisten the granule to get it to work other s wise the ants won't carry it inside the nest.  It isn't the greatest killer but it did kill a whole lot of the ants.  You could see piles of ants around the nest the next day dying or dead.  I always put sand over it the next day so innocent birds won't eat the ants & be harmed.  I have no idea if it would hurt other animals but just trying to keep them safe.  I have standard poodles and when they see me putting ant killer out, they avoid the area.  They also know that the word BUG is something that can bite or harm them.

Ants just ignored these traps even when there were huge numbers of them. Just buy a bottle of Terro PCO instead, that stuff actually works.

This product does seem to kill ants.  I purchased it to help fight an ant problem I was experiencing in my kitchen.  Once I placed the product onto the counter the ants, in less than an hour, were swarming all over it.

Some people find this unsettling but I know that just means it is working.  Plus I don't find ants to be disgusting but rather just annoying.  Anyway after a day or so they ants were greatly reduced.  However in a few days they came back again in big numbers and were reduced again.  This has been the cycle.

I believe this is because I am experiencing Argentine ants and what is happening is this product is killing off one colony and then another colony moves into the vacant space.  The key seems to keep applying fresh product and look around your house for signs of other ant activity.  Once located apply this product to those areas too.

Also don't forget to walk around the outside of your home, on a dry day, to identify any areas where ants are entering your house.  This includes checking behind all bushes and trees that up against your exterior walls.  Finally don't forget ants, and other bugs, will use shrubs and trees as roadways to your house.  Therefore you should make sure that all plants are four to six inches a way from your home's siding.

UPDATE:

19 May 2014

As stated this product is very effective indoors.  In my case I was fighting little blank ants which could be Argentine's.  I am not 100% sure either way.  This product would reduce their numbers greatly.  I would find thousands of them dead all over the basement floor.  The first time I found them I thought how did dirt get all over the place.  However when I investigated I noticed the "dirt" turned out to be ant bodies.

This product wasn't enough by itself to totally solve the issue.  True the number of ants would be greatly reduced but in a week or so here they would come again.  Then they would die off.  Then come back. This yoyoing went on for a few months and I was getting tired of sweeping up dead ant bodies.

I knew I needed a new tactic.  I had noticed these guys outside on the brick siding.  Unfortunately they are immune to the professional grade spray unlike other ants.  Yes I had placed this liquid bait near their outdoor activity but that didn't seem to be enough.  So I started doing a lot of research on how to address this situation and I found the solution.  I continued to use this product indoors and ADDED TERRO 901 Ant Killer 3lb Shaker Bag .:. Amazon ID: B001B1KGCO

The shaker bag is very easy to use and requires no additional tools to spread.  You do need to wet the product after application so put it out when it is about to rain or use another method.  I used my bug sprayer to accomplish that task.  Once this product was applied around the perimeter of the house it started killing the outdoor ants, while the Terro liquid bait killed them inside.  After about a week no more ants.  It has now been months and months since I have seen an ant indoors.

So if you are experiencing ant issues you can try this liquid bait.  If it doesn't quite seem to do the job I highly suggest the shaker bag.  The shaker bag also targets other insects like roaches, so it is a good product to put out.  In my yard I have noticed an increasing number of ants away from the house which means they could eventually reinfest the home.  So one does need to monitor the situation and keep a good active chemical barrier on the ground and walls.  I am going to target other areas away from my home as I want to be proactive.  Of course you must decide what's right for you but I would rather fight them in the yard than in the house.
