I don't know how you get a couple cc's in a juicy grape, i tried and it just gushed out, and IMO pour on can be dangerous to birds because of the insert ingredient is grain alcohol.Ivermectin can last for years past the experation date. All companies have to put a date on the product by law. Some meds can last for 15-30 years after the experation, use by or best by dates. All you have to do is google it LOL. The date just means that the maker will guarantee the product up to that year, but not after. I use pour on for cattle and I inject it into a grape if needed. Never had a problem doing it that way and you can get a smaller bottle
