How do I make a spider farm in my kitchen to eat flies in the house?
I'm not an entomologist, but...this isn't going to work. My non-expert intuition here is that spiders don't want to live in a box, and they especially don't want to live with other spiders in a box. Also, if you're going to the trouble of luring flies into a box, maybe just put some fly paper in there? Sometimes simpler is better.
P.S. The expression is &quot;you catch more flies with honey than with vinegar,&quot; but actual non-metaphorical flies seem pretty crazy about dog poop, so I don't think they're too fussy.
P.P.S. Please don't put dog poop in your spider farm.
