How to Get Rid of Moths in Wardrobes
Clothing moth infestations quickly spiral out of control, so prevention of a recurrence must always follow the elimination of this tiny but destructive pest. Control methods include a combination of chemical and mechanical means.
First: Thorough cleaning
Start by emptying the affected wardrobe and wash or dry clean the entire contents if possible. Hot water kills the insects, as does freezing for a day or two. Vacuuming and cleaning the entire area, especially wool or silk carpets, aids in the elimination of populations lurking outside the wardrobe.
Second: Chemical controls
Chemical sprays and dusts may provide relief. The treatment requires a repeat application every few weeks as most chemicals leave the eggs unscathed. Fumes from moth balls only provide control in an almost air-tight, enclosed space, and cause problems with both odor and toxicity. A professional may provide more effective treatment for severe infestations.
Third: Mechanical controls
Natural options such as dusting all cracks and crevices with non-toxic diatomaceous earth often prove quite effective, causing the moths to simply dry out. Lowering the humidity to less than 50 percent slows an infestation considerably. Vacuuming removes a large number of the pests. Pheromone-baited sticky traps catch the pests before they lay more eggs, and also provide an excellent early alert system for future invasions.
Fourth: Prevention
Because moths and their larvae prefer dark, undisturbed places, clearing out their lairs and shaking out susceptible clothing and textiles every few weeks discourages them. Seal small cracks and avoid attracting moths by never putting away dirty or sweaty clothes. Citrus-scented cleaners and cedar, lavender or camphor repellents may avoid an infestation. Enclose stored items in heavy paper or plastic bags or containers with tape around the edges to keep out moths.
