If you have ants in your house that love to find the sugar bowl, drips of soda or anything sweet, Terro will corral them, “treat” them, and eventually kill the nest.
This form of Terro comes in a small squeeze bottle. It is a clear viscous liquid. You squeeze a large drop of the product on a piece of cardboard or foil and then place it where the ants like to travel. I usually keep a spot of it in the space between my kitchen sink and the wall.
It may take a few hours for the ants to find it, but I’ve seen them find it in only a few minutes if there happened to be one or two ants nearby when I placed the bait out. As you can see in the picture, they love this product!
You will not see them drop dead in your kitchen. What Terro does is allow the worker ants (the ones you see) to live long enough to take the poison back to the nest where they share it with others. This will eventually kill the entire nest. Other products that only kill the ants on contact can not do this.
If you know the routes the ants take to get into your house you can put bait dots outside. However, it must be put where pets and children (and any other animals you care about) can not get at it.
I usually just keep one bait spot going at a time because I am patient, and it keeps them so occupied that they don’t bother other food very much, but if you really can’t stand seeing any ants around you would need to be more aggressive and put out more bait drops. Nevertheless, it may take a week or two before the entire nest is destroyed.
The package says it’s effective against the following ants: Argentine, ghost, cornfield, pavement, acrobat, white-footed, little black, odorous house, crazy, big-headed, and any other sweet-eating ants. The active ingredient is sodium tetraborate decahydrate (borax) 5.4%
The only reason I did not rate it as a 5 is that for people who want every ant gone NOW, this is not the product for you.
Terro comes in many different forms. I find this one very easy to use and there’s not a ton of extra packaging- always a positive feature in my book.
Update On Mar 08, 2010: We needed a new bottle of this, and I was having trouble finding it. It may be more available seasonally, because I just found some at Meijer yesterday. Horray! This is so economical, and it really works. I don't like all the extra packaging and stuff that the other forms have.
