Outdoor Liquid Ant Baits

I am trying to control the carpenter ants in our oak trees. I started using these last fall and they seem effective. The bait does dry out over a few weeks.

I use these outside during spring. Takes care of any ants that like to visit during that time!

UPDATE of March 27, 2025: So, I ordered this Terro Outdoor Ant Killer product, T1804-6, again on March 26, 2025 AFTER calling Terro customer service just prior to reordering. I was told by a Terro customer service rep that the ant stakes were to come with this outdoor version of Terro Ant Killer. So, I ordered again from Amazon late yesterday. I ordered a box of 12 and a box of 4. The package arrived early this morning in a PLASTIC BAG. Luckily nothing was damaged this time. There were no stakes included in either set of Terro smaller boxes. The package of 12 had 2 holes in each, diagonal from each other, but no plastic stakes. The package of 4 had no holes and no stakes. I called Terro again today and was told the stakes are no longer included. I said that I hope this message is being recorded, as I don't want to have to collect these plastic ant stakes from all over my shrub bed after the wind blows. I also expressed a safety concern for small children and pets (including squirrels, etc.). I was told that my comments of safety concerns would be submitted to the company with a request for the plastic stakes to be included in the future. Will it happen...who knows? I did let Terro know that other customers are not happy that the stakes were discontinued. In conclusion, this product works great if you can get them to stay in place. Covering them with mulch does not seem to suffice. So, now I am seeking plastic stakes that might fit the ones that do have holes in the base of each unit. >>>>>PREVIOUS comments below: Where are the stakes to secure these TERRO ant stakes in place? I've ordered many of these for years, and I've been very pleased with them; HOWEVER, those TERRO ant stakes I ordered last year had NO STAKES...zero stakes. These little round things won't stay placed near my foundation without the stakes. They wind up all around the bed of shrubs and flowers. My point is to secure them and cover them with mulch. Before I spend $25-$50 again, I want to know if the stakes and the holes for the stakes are currently included in March of 2025. Does anyone know if the stakes and the holes for the ant stakes are included once again??? AND, The spiral green version of ant stakes don't work well, because they don't go deep enough into the ground, as the stakes are too blunt...AND, the solid dark green spiral stakes do not contain as much liquid.

The only product I have found that takes care of the whole colony

Why did you pick this product vs others?: Terro just works…. Yes it kills ants, but it’s one of the safest to use around pets and young humans. Borax (soap) being the ingredient might cause some stomach issues, but they are temporary. Durability: This is my favorite design, because of the little ramps on the sides for ants to go up. Makes it very hard to spill as well. Kills bugs: Every year, this is the go-to. It attracts ants, they eat it, then take it back to their colony, and feed their ant buddies inside. This includes the Queen. Because it’s laced with sugar, it will ATTRACT ants to it, then after about 4-7 days… no more ants. Problem is, in another week or two the eggs in the colony will hatch, and there is a second wave. Keep it out there, keep it as close to their homes as you can find, and it will decimate them both above and below ground.
