Termidor SC is only labeled to be used up against a structure and not for any type of lawn application. We would recommend a product like Cyzmic CS. Cyzmic CS is a water-based insecticide concentrate that provides excellent control of dozens of insect pests in a powerful micro-encapsulated formulation with long-lasting control and little to no odor.
Both would need to be done. You should perform a trench and treat around the perimeter of the screened porch, but you also need to be concerned about the seam where the porch is attached to the house….where the beam is that you described. Any time you have an “add on” to the house, in this case the screen porch, it is possible for termites to enter between the porch and the house. Therefore, you should drill along that seam and treat with a termiticide along the house foundation as well as around the perimeter.
You will not want to touch the soil treated with Termidor SC with bare hands. You will also not want to disturb the soil after the area has been trenched and treated.
We actually recommend, if possible, to apply Termidor in a trench inside the crawl space. You will use the same method as you do around the entire structure. If you are not able to do so it might be best to contact a professional company for options.
The shelf life of Termidor SC is generally 3-5 years if kept sealed and stored in a cool, dry place.
Yes if the soil was disturbed, removed, or displaced after Termidor SC it could change effectiveness of barrier.
For Termidor SC to work on Drywood termites, you have to drill directly into the piece of wood the termites are in and inject Termidor into the wood. Termidor does not penetrate into wood, so you have to inject it into the center. It has to touch the termites to work, but the benefit is that it only has to contact a few termites, and then they can pass it on to the rest of the colony.
For Drywood termite treatments on wood, we recommend applying a product called Bora-Care. This product is applied to raw wood and penetrates further than any other product.
Yes, you could drill through the sides of the porch and treat underneath the top cover from the sides. You would also want to trench and treat around the exterior of the porch or sunroom as well in addition to drilling it from the sides. Please let us know if you have any other questions.
Termidor SC should have no effect on plants that are inadvertently sprayed with the product. It is important to read and follow the Termidor SC product label which states that you can only treat one foot up from and one foot out from where the ground meets the structure. The label also recommends that you remove or prune away plants, shrubs or tree branches that touch the structure. Vegetation that comes into contact with the structure may offer a route of entry for the ants allowing them to enter the structure without ever having come into contact with the treated area.
