HARRISCarpenter Ant Killer & Termite Control Treatment, 128oz Spray

If the sprayer doesn't work it's not the sprayer, it's the tube in the jug, which is too long and curls up over the level of the liquid. To fix the problem put on gloves, unscrew the cap and look for the plastic lockwasher that prevents the tube from coming out of the top. Carefully work it down about six inches and also straighten out the tube below it without creasing the tube. Now put the tube in the jug and replace and tighten the cap. When you pull the trigger you should feel it priming and it should spray.The product itself works well, better than professional baits, I think because with the bait the ants usually have other sources of food, so the ants don't eat only the bait, allowing the colony to survive even if many ants are killed. This product is a residual that the ants spread around the nest often killing the colony. Using this plus bait might work even better.

Works great!

Seems to have taken care of the ant issue but, the sprayer nozzle is unreliable and difficult to keep a continuous spray without shifting the container from side to side/front to back.

I have a pretty bad nest of carpenter ants in a 25 ft vaulted ceiling in my house. This area is incredibly hard to reach and I notice the ants on the ceiling and then they fall and die on the floor beneath this spot and leave wood shaving type of material on the windowsills. They crawl on my curtains, any water source they can find, the walls, and for 2 years we could not get rid of them. We have had the oak tree that touches the house professionally trimmed, 2 different pest control companies come out to treat, and each said the ceiling was too tall but they would do the best they could, and the ants never went away. Completely fed up this summer I researched a DIY product and bought this based on reviews. My husband got out a tall extension ladder, put on safety googles, gloves and sprayed the ceiling area and outside with about half the bottle. The hose on the sprayer pulls out pretty far and the spray reaches probably 15 feet. There is no strong smell, the product also dried quickly. The fact this can be used indoors and outdoors is a huge plus! The product did drip off the ceiling during drying, but I kept my dogs out of that room for 6 hours and then hand scrubbed and mopped the floor after really well. After 1 day we noticed more dead ants than ever, like the product got into the cracks and reached the nest. 1 week later, no ants crawling on the ceiling or walls! I think this product did the trick. Highly recommend!

The day this product arrived, i stopped seeing Carpenter Ants in my den !So I haven't opened the package yet.The Ants must have seen me place the order.

Just got the product. Read the reviews and hoped I’d be one of the lucky ones with a useable sprayer mechanism. Not so. Managed to spray 6 feet of space before the fun ended. How hard is it to supply the consumer with a decent sprayer bottle? I am heading for the basement to find a half-used sprayer bottle of roach killer. Will have to transfer this before I continue. I am very not impressed!

Works great at eliminating the big black carpenter ants that have been making their way into my house for the past two summers. I spray around the perimiter of the house, the base of some maple trees near the house, and around the edge of rooms where I have seen the ants. The day after application, I can find numerous dead ants in the rooms where I sprayed around the base of the walls. For the rest of the warmer months, after repeated application of the treatment every 2 to 3 weeks until the container is emptry, I no longer find carpenter ants anywhere in the house.

Before buying, search the reviews for the issue of the nozzle not working. There are tons. Instead of implementing some QC and fixing it, the manufacturer has put a QR code on the package to take you to a video "if" (read "when") it doesn't work. The QR takes you to an inactive webpage. I searched for the video that was supposed to have been there, read these reviews & all sorts of other info, and then tried everything else I could think of (a neighborhood handyman tried as well). Never got even a single spray out of it. Returning now.
