I have a split level home. The front side is 4ft below grade to the lower level floor. Do i still apply termidor using the trench method at the standard mix to treat for subterranean termites? A stump near my house had a swarm last week and just trying to treat my home for piece of mind.
Yes, you would still apply Termidor SC or whatever termiticide you are using in the 6 in x 6 in trench at the standard rate of 4 gallons per 10 linear feet. Where you would apply additional product would be where there are footers, where you would use a termite rod or hollow tube to apply additional product from grade to the top of the footing. Per page 7 of the product label: When the footing is more than 4 feet below grade, the applicator has the option to either (1) trench and rod to a minimum depth of 4 feet into the trench along the foundation walls or (2) trench alone along the foundation walls to a minimum depth of 4 feet. The actual depth of treatment will vary depending on soil type, degree of compaction, and location of termite activity. When the top of the footing is exposed, the applicator must treat the soil adjacent to the footing to a depth of 4 feet but not to exceed the bottom of the footing. DO NOT treat a structure below the bottom of the footing.
