Termidor Foam can be applied to voids for spot applications as directed.
When treating fences with Termidor FOAM, you will inject the foam in to the holes and can use a putty knife or spatula to spread the foam if needed. The product label states the applicator must ensure the application dissipates completely into the wood so the foam is not left exposed for non target insects or animals.
Termidor FOAM comes in a ready to use formulation whereas Termidor SC is a liquid concentrate that has to be diluted with water, so that is the reason the percentage of active ingredient is different. You can absolutely add a foaming agent to Termidor SC, but both products would render the same results.
Termidor FOAM can be used to treat inside where you can directly spot treat active infestations and Termidor SC would be used in a trench (and in drilled holes in concrete) around the home. We have a step by step guide that will walk you through how to do your own termite trenching treatment.
Yes, you can treat this infestation using Termidor Foam. You will need to drill into the infested area to apply the foam. Termidor FOAM expands rapidly creating a dry foam that can be applied in the voids, harborages, galleries, and nests where insects are found. The foam generated has an expansion ratio of 30:1. In about 5 seconds 1 oz. of product becomes approximately 1 quart of foam. For more tips, we recommend to read over step 1 of our article on How to Get Rid of Subterranean Termites.
Termidor Foam uses a non repellent active ingredient Fipronil. Thiis active ingredient works slow because it allows the active to transfer between termites so it can spread throughout killing more than just the termites that come in contact with the residual.
We would not recommend use of a product like Termidor Foam in the kitchen for treating ants. You may want to use an ant bait gel instead. Our Indoor Ant Kit would help cover the ants dietary needs of sugar and protein, as well as an insecticide you can spray around baseboards, cracks, crevices and any other entry points including under the kitchen sink. We also have a great Ant Treatment Guide that can help guide you to effectively get rid of these ants.
Termidor Foam is not labeled for yellow jackets. Termidor SC may be used for yellow jackets found on the exterior of a structure or within 1 foot of the foundation. Please see the product label for complete instructions. Please visit our Yellow Jacket Control Page for more information and for products approved for this use.
We would also suggest that you take a look at our Termite Guide for tips on how to treat and prevent an infestation in your home.
You can use Termidor FOAM in the wood post. You would need to drill directly into the galllery where the drywood termites are infesting and foam into it as directed on the product label.
