A heater for eradicating insects can include an elongated housing that includes a sidewall that extends between spaced apart first and second ends. The housing includes an inlet at the first end configured to intake ambient air and an outlet extending radially through the sidewall adjacent the second end. A fan within the housing includes blades and a motor. The blades are located between the motor and the inlet, and the motor configured to rotate the blades to move the ambient air from the inlet toward the second end of the housing. A plurality of heating elements are mounted within the housing at a radial position that is adjacent the sidewall and at an axial position that is near the outlet. A controller is configured to control the fan and the plurality of heating elements to produce outflow of heated air from the outlet with a predetermined temperature and for a duration sufficient to eradicate insects.
