Which of the following is NOT typically a method to control fabric pests?

Leaving items untreated is not a recognized method for controlling fabric pests. Effective pest management relies on proactive measures to eliminate or mitigate infestations. When dealing with fabric pests, like moths or carpet beetles, allowing items to remain untreated can exacerbate the problem, as pests can continue to feed and reproduce, leading to further damage.

Insecticidal dusting and fumigation are active intervention strategies that directly target and kill pests, while removing infested items helps to eliminate the source of the infestation. These methods focus on controlling current infestations and preventing future ones, while simply leaving items untreated can result in a worsening situation without any effective mitigation of the problem.
