What is a common method to monitor termite activity?

Setting traps with pheromones is a common method to monitor termite activity because it effectively attracts termites to specific locations where they can be observed and evaluated. Pheromones are chemicals released by insects that can signal others to gather in certain areas, making them a valuable tool for monitoring populations. This method allows professionals to determine the presence and level of infestation, which is crucial for developing an effective treatment strategy. Using this proactive approach can help identify issues before they develop into more significant infestations.

In contrast, visual inspection only involves looking for signs of termite damage or activity without the aid of attractants or monitoring tools, which may not always yield accurate or timely results. Installing motion sensors is not a commonly employed strategy in termite monitoring, as these do not specifically target termite activity and may not provide useful information about infestations. Creating barriers around structures is primarily a preventative measure rather than a monitoring method, as its purpose is to deter termites from invading rather than to observe their activity.
