The Almond Moth is an occasional pest of stored food products, infesting most grain-based products as well as dried fruit and nuts. The life cycle is completed in less than 60 days, with multiple generations occurring each year indoors. It may be most common in the U.S. in California and Florida as ports of entry as well as in California’s huge fruit and nut industries. It is tropical in origin and survives best in warm climates. Females deposit up to 300 eggs on the material the larvae will feed on. The adult moths do not feed.
Pheromone traps are very useful in trapping adult moths and narrowing the search for the infested materials. Finding the source is necessary as this is where the larvae are feeding and where new adult moths will come from. Once isolated the infested product can be disposed of or treated in some manner, the area around it thoroughly vacuumed to remove debris and wandering larvae, and if necessary a labeled residual material applied to intercept any larvae that were missed. Adult moths can be removed with a vacuum or killed with a light mist of pyrethrum.
