A method of making a mulch for eradicating termites without poisoning the soil includes spraying at least one of tree bark and wood chips with an aqueous concentration of a borate salt in a concentration sufficient to produce a mulch ineffective in protecting the mulch form infestation by termites and effective in killing termites in a colony remote from the mulch. The belt drive mechanism is comprised of a drive pulley, a driven pulley, and a timing belt, which is stretched between the drive pulley and the driven pulley. The example apparatus also includes logic for producing an evaluation of the CSC and logic for determining an expiration criteria based on the CSC, the evaluation, and the user. The subject image data is generated by imaging the imaging region in a state of the subject presenting in the imaging region.
