Various wide-spectrum chemical acaricides have proven effective for controlling tick populations, but many of these have potential deleterious side-effects on health and the environment. In addition to chemical acaricides, certain compounds such as diatomaceous earth have been shown to have physical acaricidal properties. We hypothesized that dolomitic lime (CaMg(CO<sub>3</sub>)<sub>2</sub>, a corrosive, desiccant mineral that is already used extensively in agricultural and forestry contexts to balance the pH of soils, may affect ticks' locomotory activity, habitat position, or survival and that this should manifest as a reduction in the number of questing ticks collected by dragging. <b><i>Objective:</i></b> This study aimed to formally assess this hypothesis in a controlled laboratory setting. <b><i>Methods:</i></b> We carried out a microcosm experiment, with one control and three treated microcosm trays, each replicating the natural substrate characterizing <i>I. scapularis</i> habitat in northeastern North America.
