A method for inhibiting methane production in the digestive tract of methanogenic Archaea (e.g., termites, other wood boring pests). The inhibiting of the critical biochemical pathways specific to the methanogenic Archaea is achieved by having the methanogenic Archaea ingest an anti-methanogenic compound. The anti-methanogenic compound may include, for example, naturally-occurring statins or derivatives thereof, linoleic acid or related compounds, essential oils, or some combination thereof. The naturally-occurring statins can be found in the red yeast rice extract or related biomass. As a result, the effectiveness of the methanogenic Archaea to produce methane is compromised, which subsequently results into the malfunctioning of the xylophages' digestive system. This provides a safe, natural, green and sustainable means of controlling many pests such as the Asian Beetle, Emerald Ash borer, Weevils, Deathwatch Caterpillars, and termites.
