We recommend trenching with Termidor SC because it binds to the soil and creates a continuous barrier. Most members of termite colonies remain hidden and there are often multiple colonies, so if you only treat one area where you visibly see them, there is no way to ensure that all the termites will encounter the amount of Fipronil needed to eliminate a colony. While Termidor does have a transfer effect, the idea is to create a barrier and as the termites travel through the treatment, they will absorb enough of the active chemical used in the treatment and then die.
To treat areas with Termidor SC that have a soil to foundation interruption such as a patio, you would drill holes in the patio using a ½ diameter concrete drill bit that is 18-24 inches long. The holes will be drilled every 12 inches and filled at a rate of 4 gallons of finished solution every 10 feet, just like you were doing in the trench.
Termidor SC does not bond to mulch the same way it bonds to the soil. When applied to the soil per label instructions, it will bond with the soil to remain effective for up to 10 years.
Everywhere you dig you will follow the method of digging a 6x6 trench and use 4 gallons of Termidor SC solution for every 10 linear feet of trenching.
Termidor SC is not labeled for fleas and it is also not labeled for use in a lawn so it is not what we recommend for outdoor flea control. Suspend SC is labeled for fleas and for indoor use, but it is not the best choice for indoor flea control because you can not broadcast spray it over carpeted areas. We recommend you use our Outdoor/Indoor Flea Kit to get rid of fleas in and around your home. Please take a few moments to review our article on How to Get Rid of Fleas 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 outside within 1 foot of a house or other structure that we are trying to protect. You also should not apply Termidor SC near or on edible plants. The supplemental label of this product does allow for treatment of active carpenter ants in landscape timbers: in this case, the Termidor SC finished solution would need to be injected into the wood where the ants are found. A safe option for use around the outside of the raised bed would be to use a bait such as Advance Carpenter Ant Bait Granules.
When getting ready to treat with Termidor SC and digging a trench, you can use whatever equipment you have at your disposal as long as you’re able to safely trench the perimeter of your home. Also, when trenching and if it rains, you could use a tarp to cover up the area to protect what’s already been done.
