sun. that way i am sure something will get it. the sun. ants. birds.
they usually only come out in the early morning or late evening, to stay out of the sun.
i have been blessed with mocking birds that keep me horn worm free. most of the time. guess they me be falling down on the job. use the whole decals (they are too big anyway) for more than just one nail.
oh and i applied them over my previous manicure, it started to chip so i played the 'i'm super lazy' card and just applied them over it. and now i have a fresh manicure ;d.
