No, Termidor SC will not kill your tree, however, it is not labeled for use on trees or any other vegetation. This should only be used around the perimeter of your home.
Termidor SC is a great exterior product for ants including carpenter ants. It will last for six months as a topical outdoor application but can take some time to fully eradicate as the ants carry it and transfer to other colony members. You will be able to get rid of Carpenter Ants more effectively if you can locate where they are coming from. They are the most active at night between 10AM-4AM. We do recommend treating with the Maxforce FC Carpenter Ant Bait and the Advance Carpenter Ant Bait. These baits will be extremely effective. The granules should be applied when dry outside and you are not expecting any rainfall within 24 hours of application. The bait gel can be applied directly to indoor cracks and crevices once every two weeks.
When applying Termidor SC to a home with a raised foundation, you would trench around the outside of the foundation and around each pier/post under the crawlspace. Everywhere you dig you will follow the method of digging a 6x6 trench and use 4 gallons to every 10 linear feet. Termidor needs to be trenched in order for it to be effective and cannot just be poured onto the ground.
Termidor SC should not be applied for treating stinkbugs. We do offer an Overwintering Kit for Stinkbugs. Please take a few moments to review our treatment article on How to Get Rid of Stinkbugs for a successful eradication program.
Termidor SC should not harm plants when used as directed. Treatments should be kept within 1 foot of the foundation though.
Termidor SC should only be applied to the exterior (1ft up and 1 ft out) directly up against the structure only. You will mix 0.8 fl oz per gallon of water and apply once every 6 months. For more information on treating ants, please check out our treatment article.
Termidor SC can only be applied around the foundation of your home or other building structure for control of ants and other listed insects. You cannot use the product out on or around the trees or fences because it is not labeled for this type of application. We recommend using our most popular product for spider mites, Talstar P. Talstar P is known to have a pretty good miticide effect for these plant-infesting pests. When Talstar P is over-used the mites are known to build up a resistance to the active ingredient. The other choices would be to use a Horticultural Oil or an insecticidal soap. Both of these products work best when they make direct contact with the pest and both products are known to cause discoloration to spruce trees. The pro to using one of these products is that spider mites cannot build up a resistance to them.
Termidor SC is not specifically labeled to eradicate nematodes but could cause harm to them. We do not suggest using the same applicator or in the same areas.
Termidor SC is what we call a non-repellent, which means the insects - in this case, ants - do not detect the application, plus the active ingredient kills slowly enough that the ants do not die until they've had time to pass along the active ingredient to all the other ants they contact during their regular activities. If you apply Termidor SC as directed, then any ant colonies that contact that barrier will be killed. If you are already seeing trails of ants inside your home, then we would recommend using products like those in our Indoor Ant Kit to insure those colonies are taken care of, as well. Our Ant Treatment Guide has additional tips for treating this nuisance pest.
