Like, for one thing, spiders are catching other bugs for a purpose, not just to torture them for fun, durr. Aside from the fact that was, entirely not, the point of my response. How freaking daft can you be?
"Spider mites...and gnats..." would be inclusive of the OTHER BUGS I was referring to... and way to attack the straw man. FYI, I use predator mites which also eat fungus gnats, spider mites, collembola, etc.
If you can't see the difference between predation for survival (and among bugs no less) and deliberately harming a much larger, more intelligent animal (smarter than you) which can be dealt with in an altogether different, more responsible, humane manner: you are dumb and pathetic and there is nothing I can do for you, and I am sorry.
Otherwise, the point is I learn to co-exist with things that do me no harm, and especially the things which I know for a fact possess a certain level of intelligence and do not need to be harmed out of spite. Including harm I may ill-perceive or otherwise exaggerate or harm I myself can prevent from being incurred upon myself. But, then there are organisms which undeniably harm [plants or organisms] or which are "invasive". Ancestors of mice\rats were dwelling on this site long before my ancestors, a native part of the habitat unlike any Japanese Beetle.
So if there is a spider that I don't want around me just because and I catch it in a jar and put it outside, whereas I kill the Japanese Beetle, that doesn't make me anything close to a hypocrite.
