Like many other phobias, lilapsophobia can often be treated using cognitive-behavioral therapy, but if it stems from post-traumatic stress disorder, then alternative therapy may be more recommended.

Lilapsophobes spend a lot of time watching the weather or checking weather online to keep an eye out for oncoming storms. When a storm hits, sufferers either watch for severe weather alerts constantly or take cover, like under the bed or in the windowless room. In the extreme cases, sufferers take tornado shelter as soon as rain starts falling, usually in the basement or storm shelter. Sufferers who have weather radio or mobile phones can watch the radar and alerts using it while hiding.
