When applying Termidor Dry, the openings should be approximately every 24" or into each void. The tip of the Termidor Dry is only about 1/8 of an inch in size and the hole the product comes out of on the tip is even smaller. However, no matter how small the tip is you must drill into the holes to ensure the product penetrates into the galleries for full treatment reach. Large holes are not necessary but using a small drill bit for a pilot hole would be needed.
We have Termidor DRY but you will need an applicator to apply it. Termidor DRY - Starter Kit comes with two 5-gram vials of Termidor DRY, and one Termidor DRY Applicator. Other Termidor concentrate formulations besides Termidor SC in the 20 ounce bottle are only available for purchase by licensed Pest Control Operators.
Termidor DRY will be more effecitive than foaming as it travels further through the walls.
The Termidor DRY Starter Kit includes (1) applicator, (2) 5-gram vials of Termidor DRY and a clear plastic tube.
When using the Termidor DRY - Starter Kit, it is recommended to wear protective gear including: chemical resistant gloves, goggles, protective suit and a NIOSH-certified (or equivalent) organic vapour/particulate respirator. We do offer safety kits with these items included.
