We have a screened in shack in the back yard and at this time of year on warmer sunny days get hundreds if not thousands of Lady Bugs on the south side screens. Most of them are on the inside of the screens and can be a real nuisance when eating our meals. I think they get into the shack by entering the corrugations in the tin roof and emerging between the roof boards. They can also bite. Anyone else get this many Lady bugs?
