What is an appropriate method for preventing moth infestations?

Regularly inspecting and cleaning stored fabrics is an effective method for preventing moth infestations because it helps to eliminate potential food sources and breeding grounds for moths. Moths are attracted to natural fibers commonly found in fabrics, such as wool, cashmere, and silk, especially when these fabrics are soiled or contain food particles. By routinely checking and cleaning these items, you can remove any eggs, larvae, or adult moths before they establish a more significant problem.

In addition to cleaning, it's important to ensure that any items being stored are properly packed and that storage areas are kept clean and dry to further deter infestations. This proactive approach can significantly reduce the likelihood of moth activity in your home.

Other methods mentioned, like using mothballs and only treating after an infestation is suspected, might not be as proactive. Mothballs can help in controlling existing infestations but are not a preventative measure by themselves. Leaving closets closed for long periods could create an ideal environment for moths to reproduce undetected.
