I have an ant infestation in my orchid house. (Lovely thought, right?) What concentration do those of you who use this with orchids use? Thanks!

I would use no more than 2 tbsp per gallon of water. If needed increase to 3 for bad infestations

I use 1 teaspoon per gallon, but you have to apply it at least 3 times, about a week apart each time. Orthene is a systemic, so eventually the plant has enough to fight off most infestations. To prevent future infestations, use 1 teaspoon per gallon applied twice, about a week apart each several times throughout the year.

I had ants marching from behind a kitchen cabinet. They were heading in two different directions. I located where they were coming out from behind the cabinet. I ran a bead of Terro so they could not come out without walking thru it. The ants walked thru it, and about 2 hours later they were all over the wall. The next day they were all gone. Have not seen another one in over 43 months.

Don't buy it. It is so toxic, really. Not worth it for your own health and the environment. I would place the orchids in a window with direct sun for a few weeks, or I would use a toothbrush and some dishsoap in water to clean the surfaces of the plant (if mites/larva are the problem). Steer clear of such harsh chemicals though. This is banned in Europe. It is what is causing the honeybee collapse in the US.

I think that simply using it as directed will get better results. Near the ant trail squeeze out a glob about the size of a green pea. The ants love the stuff and go out of their way to bring it back to the colony. I wouldn't dilute it.

Only wood destroying ants in wall void. You need to read label on application of product. We use it for wall voids and it works very well.

the information that comes with the bottle has instructions for this. DO NOT APPLY this chemical as it comes from the manufacturer, it is too concentrated. If I remember correctly for ant hills you make a 0.12 or 0.06 % solution and "inject" a lot of it directly into the colony or hill and then use a 0.03% solution to spray the area around the hill to kill all remaining ants that were out working.

M batch has worked fine. I did go through two of the tubes before I was ant free. Additionally, the colonies seemed to relocate once they figured out they weren't able to sustain the colony after I applied the bait. So I had to be vigilant about searching for active ant trails in the early evening and running a couple of beads of the bait. It took a good two to three weeks of putting down the bait every two or three days before we were ant free in the house. However, if you feel it's just not working I"m sure you could contact the manufacturer and request a refund.

Yes! I mainly use it for sugar ants. Let them take the bait back to their "nest"...meaning...you need to let them crawl around for a day after leaving the bait out without killing them. Once it's been out for a day or two you will notice...no more ants. Many months later you may notice a return, if it's a problem area but you'll have the Terro on hand!

The product was designed to work best for subterranean termite control. Try Beneficial Nematodes for ants. Spray right on the moving ant trial. Bye Ants!!!!

I have used it successfully with those really small "sugar" and "ghost" ants that come in the house. It also worked on the larger ants going up the wall of my home toward the roof. I really bought too much--I still have quite a bit left and have only had to retreat 2-3 times since I bought it at least several years ago.

Larry, I used it on black, red, & fire ants. ( it doesn't go far & neither did they) I put a little at the base of an oak tree that has carpenter ants & it did kill some. Sorry I couldn't help more.

Demand Cs is my go to product. Normally I wouldn't use it for carpenter ants. Termidor Sc works better in killing entire colony.

It's not recommended for inside use without taking proper precautions. I've found if you take care of the ant problem outside you shouldn't have ants inside. If you do, you could spray with a product safe to use indoors. I wouldn't think you would need to spray after a rain unless it rained immediately after spraying. If you have a return of ants after some time has passed since spraying you may have to spray again. You didn't indicate what kind of ants you have. That can influence the method of control you use. The use of a bait that the ants carry back to the nest is quite helpful also. Hope this helps. It's not recommended for inside use without taking proper precautions.

Yes, it will. It works as an immediate killer of bugs on most plants, and also as a systemic insecticide. That means the roots absorb the chemical and continue to kill insects feeding on it. It probably won't work effectively as a systemic on orchids and may take more than one application. Please also read this: http://forums2.gardenweb.com/forums/load/orchids/msg1216493017931.html

I don't know about this particular infestation, but I have used the product on my orchids, over several months, and they are thriving. The fungus gnats, my original concern, are well controlled.

I've used it several times on fire ant mounds, it seems to be pretty effective,, whether it's more effective than some of the other products intended solely for that purpose remains unclear. I will say this though we had an issue with carpenter ants in our house that were almost impossible to stop , even our pest control company couldn't put a stop to the ants. Since I started spraying the Demon product pretty heavy around the perimeter 3 or 4 times a year we no longer have them inside the house.

I don't know, for sure but I'm guessing around 6 or 8 oz... but you use only a very small drop or two of it, in places where you see the ants going to and from their nests. They smell it (I guess) and are immediately attracted to it--even as you're putting the drops down they are all over it. It's pretty amazing. Then they take it back to the nest and it kills off the colony.
