Fall Armyworm

Fall Armyworm

Spodoptera Frugiperda

An adult female can lay about 1,000 eggs in batches of about 100 during her 12-day life cycle.


If Fall Armyworms are present, it is very important to treat with an insecticide as soon as possible because they feed rapidly and are very destructive.
