I found an old can of Rislone 710 (probably circa 2004) in my garage and I opened it for S&G just to see what it looked like (never planned on using it and dumped it into my used oil bucket) and there was a dead fly floating in the top of the can! It was clearly sealed inside the can when it was made and had been inside for quite some time. It was submerged in the additive like a bug inside amber lol. Makes you wonder about their quality control practices back then.
