Termidor Foam can be applied to voids for spot applications as directed.
The consistency of the Termidor FOAM when expanding is similar to a high volume hair mousse that will disipate slowly after injected into the space. It is not a hard foaming expansion foam so should not cause damage to any doors or joints.
Please view our How to Apply Termidor Foam Video for a quick demonstration of how the foam looks and is applied.
For further technical information, please reach out to the manufacturer BASF at 770-985-9195 regarding this matter.
Termidor FOAM will not cause issues with electrical outlets or molding when used per the product label. You can view our video on How to Use Termidor Foam that may help.
It can take up to 90 days for an entire termite colony to be eliminated after a treatment with chemicals such as Termidor Foam. Due to the difference between the way the ingredients work to control the colony, you would need to give time for the Termidor to kill the colony before the Boracare is applied. You'd want to wait at least 60-90 days before applying it to the existing wood for protection.
Termidor Foam is an expanding foam that will start to disperse after it fully expands and will leave behind a residual that will continue to kill termites for about 6 weeks following the application. Termidor FOAM will expand at a ratio of about 30:1, so each 20-ounce can will create about 20 quarts of foam, covering approximately 1,155 cubic inches.
Termidor Foam can be applied to wall voids where suspected termite or ant activity is found, and as long as you are not drilling into the wires behind the wall, the foam would have no impact on the materials it may come into contact with besides the termites.
