Sometimes I think we need a sticky thread for "feeder disasters" where we can all add our stories.
Oh let's see, there's the time my blue bottle fly order was delayed so by the time I picked them up at the PO the box was vibrating/buzzing so loud the postmaster wondered if it might be a bomb.
And, the night my dubia roach colony held a dance, rocked its Rubbermaid tote off its shelf over the boiler, and released who knows how many hundreds of nymphs and adults. Of course the colony happened to be at its production peak at the time. I discovered all this the next morning while leaving for work. Found live, dying, and dead roaches all over the house and crawlspace for months.
Then there was my first delivery of 500 European nightcrawlers who lived up to their name. I set them up in an open topped bin with a nightlight hanging overhead to keep them from escaping. The bulb burned out in the middle of the night and they were off. Woke up to hundreds of cold slimy things all over the bedroom carpet. I found dying and dead worms in my closet, under furniture, cabinets, and bookshelves for a week or so. Who would have thought keeping worms would be so hard? I now have great respect for the determination of all worms.
Because of where I live I try to round as many of them up as possible. All I can think about is how much each of them cost to get here!
