What depth do I use to measure the 65 degree soil temp to apply Extinguish Fire Ant Bait?
Yes to use Extinguish Fire Ant Bait,†you should only apply this if the soil temperature is about 65 degrees. In order to check for the soil temperature†most thermometers will instruct to insert the thermometer to a maximum depth of 2" to 3" and leave it for a certain amount of time, you can find these instructions on the soil thermomether you decide to use, we carry a Luster Leaf Rapitest Soil Thermometer.
