Treating Removed Trench Soil - back fill when wet or dry?

Your video states to wait until the Termidor has dried in the trench, then treat the back-fill with Termidor as I fill in the trenches. However, others mention I can backfill while there is still Termidor fluid in the trench and mix it in, while wet. Is this method acceptable? I was planning to do a 10 foot section at a time, and then back-fill right after I poured the treatment in while there is still plenty Termidor to mix it with.


Once the trench is filled with the proper amount of termiticide, cover the trench back with the dirt that was removed. You want the dirt that you place back in the trench to be treated also, so that you have a complete barrier against your house and no untreated soil. If you place the dirt back in the trench while it is still filled with the termiticide, it will mix and be treated. If the ground has already soaked up the termiticide, than you will need to pour extra termiticide on the backfill as you are pushing it back into the trench so it will be treated also.
