I'm starting to get some ideas for aphid removal. Removing aphids simply by raising earwigs might displace wasps in the yard. Good link!!

Seems something they should have figured out long before now  And it makes sense, few things look more predatory than an earwig!  

 Now I remember Ted Swenson, at a Fall or Spring event, probably both, sitting at the information table waiting for people to ask him what the clay pot, stuffed with newspaper, on a rope was. He'd grin and say it was an earwig house (hotel?), to hang in your fruit tree (looking like a bell, open end down), a conversation starter for sure. Seems like a coiled strip of corrugated cardboard (as in the article) would be inviting as well. If memory serves, leave it on the ground for a few days to get inhabited, then hang it where convenient for the critters to exit at night and return during the day.

I'm going there.... forgetting about this for long enough, and watching my plum tree year after year getting hammered. The lady bugs always show up but not until the population of aphid is overwhelming; and recently, last couple years, wasps or yellow jackets, I think not just enjoying the honeydew. Maybe another bit of a strategy to be employed.

I'm late to this, but thanks for the share! Like Viron said, I'm surprised no one stumbled on this earlier. I remember these things scaring the hell out of me as a kid! Haha. Maybe if I can get past the phobia I'll think about introducing some...
