How long do you bake soil to kill bugs?
Bake in a preheated oven (200°F) until the temperature of the center reaches 180°F (use a meat thermometer to measure). Once the temperature reaches 180°F, bake for 30 minutes. Do not overheat or overbake since it can release toxins harmful to plants as well as kill beneficial organisms.
How do you sterilize soil with heat?

What happens if you bake dirt?
Commercially, soilborne pathogens are removed by a number of techniques, including solarization, fungicides, fumigation and heat. For home gardeners who need to remove pathogens from a small amount of soil, baking soil in the oven is an effective technique and the soil is safe for planting as soon as it cools.
How do you sterilize large amounts of soil?
