What is the best preventative measure for field crickets entering a structure?

Maintaining grass and ornamental areas is indeed the best preventative measure for reducing the likelihood of field crickets entering a structure. Keeping these areas well-trimmed and free of debris minimizes the potential hiding spots and breeding environments for crickets. Since field crickets thrive in tall grass and dense foliage, regular maintenance disrupts their habitat, making it less inviting for them to approach buildings.

While options like using ultrasonic devices and regular pest fumigation may sound appealing, there is limited evidence supporting the effectiveness of ultrasonic devices in repelling or controlling crickets. Fumigation, on the other hand, is more of a reactive measure rather than a preventative strategy and can also have broader implications for other beneficial insects and the environment.

Placing screens on windows is a useful practice for preventing pests from entering but does not address the initial attraction to the structure, which is often influenced by the surrounding landscape. Therefore, proactive landscape management stands out as the most effective method for preventing field cricket invasions.
