How to treat each type of area 6

horizontal treated zones (soil surface)

Location Rate Unit Dilution Label notes
Outdoor 1.0 to 1.5 gallons Termidor H•P II finished dilution per 10 square feet using a nozzle pressure of 25 PSI or less and a coarse application nozzle (e.g., Delavan Type RD Raindrop®, RD-7 or larger, or Spraying Systems Co. 80110LP Teejet® or comparable nozzle). DO NOT broadcast or power spray with high pressure.

horizontal treated zones (through foundation wall or floor)

Location Rate Unit Dilution Label notes
Outdoor 1.0 to 1.5 gallons Termidor H•P II finished dilution drill (no wider than 18 inches apart) through the foundation wall or through the floor above and treat soil adjacent to the foundation wall per 10 square feet. Soil adjacent to foundation elements may be treated with short-rodding or long-rodding techniques without drilling if access for treatment tool to soil site is available.

sump pump pit

If water is in the sump pump pit, unplug the sump pump and remove four cups of water from the sump pump pit. Mark the water level. Wait 10 minutes and check the water level in the sump pump pit again. If the water level has risen, there is too much seepage to perform the treatment at this time. If the water level does not rise, make the treatment provided the sump pump remains unplugged. During application, check the sump pump pit every few minutes for the presence of Termidor ® H•P II High Precision Termiticide finished dilution. If detected, stop treatment immediately and remove the contents of the sump pump pit before plugging in the sump pump again.
