You already know how I process my hops, so no need to repeat here. Feel free to put them in the boil, but you really need 5 times as many by weight. The boil will kill any yeast, bacteria, or critters. If you add them late you really need a pile of them and consider if you can drain your wort out of the boil kettle. I have had many insects fly into my wort. Heck, hamburger and hot dogs can legally contain rodent hairs! Don't worry, get brewing. The alcohol will probably sanitize the dry hops. Just think of the critters as a "worm in the bottom of a tequila bottle". Wet hops are not predictable. If you want to spend your brew day making an unpredictable beer that you wont be able to duplicate, have a ball. It is like decoction, at least you can say you did it once! Have fun!
