In 2021, in the middle of the summer, we were infested by the Army Worm.  This was the first time they had migrated this far north.  Normally they would only get as far north as Columbus, Ohio.  The hot temperatures, dry weather, and a strong northly wind brought them up as far as Geauga, Trumbull and Ashtabula counties.  They showed up overnight and wiped out lawns in the matter of a day or two.  I received close to one hundred calls to treat for their infestation.  In 2022 and 2023, they have not appeared this far north.
