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.
Termidor SC should not harm plants when used as directed. Treatments should be kept within 1 foot of the foundation though.
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.
Cy-Kick CS is a great product, but Termidor SC is the preferred product for your situation. Termidor SC is a non-repellent insecticide that also has a transfer effect, this means that the ants will not know that Termidor SC has been applied, and therefore cannot avoid the treated area and as they come into contact with other ants they will spread the insecticide and wipe out the colony. Termidor SC can also be used for drywood termites. It is important to remember that you must apply the product into the spaces that these termites will actually come into contact with it. That could mean that you would need to drill into the wood or possibly even foam the product into the space.We have never had a complaint about the smell of Termidor SC and the MSDS says that it is odorless.
Termidor SC should not be applied through a hose end applicator for application to the lawn and flower beds for ant control. It should only be sprayed a couple of times a year directly up against the foundation of the strucutres on the property (1 ft and 1 ft out). We would recommend using Arilon Insecticide. It can be used around the perimeter of the home and you could expand the band around the perimeter, for example: you can spray 3 feet up on the foundation and 7 feet out. The active can also be transferred from one ant to another and can be used for direct mound treatments if necessary, as well as surfaces commonly used by ants for foraging such as outdoor edges/frames of windows, doors, utility penetrations, roof lines or eaves, and other structural edges may also be treated. In addition to exterior structural elements, outdoor nesting sites such as refuse collection areas, flower/mulch beds, adjacent tree holes, surrounding turf areas, crawl spaces, or other nest/ foraging sites, and foraging trails can be treated.
Termidor SC when applied to wood would only last about 90 days and would not be used as pre-treatment for wood.
Bora-Care is usually the preferred choice for pre-treating wood that is exposed and it is raw wood you are treating, meaning it is not painted, stained, or sealed, it is just normal wood. Bora-Care is made only for wood. Bora-Care is sprayed evenly over all exposed surfaces of the wood and actually penetrates through the entire piece of wood. For frame up, you would apply to the bottom 2 feet of wood.
