I two have them...I have holes all over..so to spray into everyone will be inpossaible.. Have you found a solution yet.. And if so did it work... I did read in other site about buying a couple of plastic knifes placing in each hole at night and as you spray into them...and in the morning if any new hole are present them remove the old and so on until there gone.. I been dealing with them for about a few years now and I hadn't seen then last year.. But THERE BACKK this year and more then ever I know HELPPPP TOOOOOOOOOOOO.
