Starting last night I discovered small brown 1/2 inch long "worms" or inch worms crawling all over my driveway, sidewalk, front doors and garage doors. Now they are still there on the 2nd day. Checked with the neighbors and 2 other homes have them also. Have no idea what they are but it is unseasonably warm in Cincinnati. Not sure if they are larvae hatching due to the warm soil but they also give off an odor. HELP!! They are gross crawling all over the doors. Could they be coming from the mulch that's been there all summer long??
