Which method is NOT part of an earwig management program?

Planting onions to repel earwigs is not recognized as an effective method in managing their populations. While there are some plants known to deter various pests due to their scent or properties, onions have not been scientifically proven to influence earwig behavior or reduce their presence.

In contrast, trapping with jars or tin cans baited with fish is an effective method, as it takes advantage of earwigs' attraction to certain baits, allowing for their capture. Reapplying insecticide applications is a common practice in pest control, ensuring that any lifecycle stages of the earwigs are effectively targeted. Mechanically removing earwigs when found in homes is a hands-on approach that helps reduce their numbers and prevent further infestation. Each of these methods contributes to a comprehensive management strategy for earwigs, while planting onions does not align with established pest control techniques for this particular pest.
