I've got a wee 100 sq st garden plot, and an astounding number of bugs. There's a healthy population of lizards around here (Northern Cali) to help keep them down, but unfortunately, lizards don't lay chicken eggs, and I could use chicken eggs as a bonus to bug control since there's a lot of slugs, pillbugs, beetles and the such around here too.
John; I'm already farming the bugs. My garden bed is raised and I have boards lining the bed, resting at an angle. Bugs congregate in the crevasse, where it's easy to pick and drown them... also have several paving stones about the yard that collect sowbugs, slugs and beetles like crazy.
Boddah; I don't have a problem with bugs until they start eating my garden contents. Well, except for slugs. I really disdain them for some reason. If all the beetles were lady bugs, I'd be a happy camper.
I have a circle of crushed eggshells around my plants; as long as the slugs don't trespass past my little calcium moats, I don't care where they go particularly. However when I see little glistening slime trails criss-cross inside my barrier... well, that I find very irksome. I'm all for depleting a slug colony that destroys my seedlings... I'm not growing veggies for bugs to decimate. I have the pavers about so they'll congregate under them and away from the garden (in theory).
My feelings on it is that if myself or a flock of fowl take on bugs (specifically the ones that eat my plants), odds are enough of them had already laid eggs to help propagate the species by the time I get to them. While my attempts to keep the population down might actually reduce the numbers, I don't think I'll make them extinct in the backyard anytime soon. Having fowl do the dirty work is in my opinion, having the circle of life be complete (and I get eggies as a bonus).
For my next feat, I will require a volunteer from the audience! Perhaps this tiny ad?
