The Seek app by iNaturalist is great. It's really good at identifying pants and animals and to a lesser degree, fungi. It's also used for research, so it's pretty cool. My wife and I always update each other on how many new species we snapped at the end of the day.
Close all windows and doors, set off the required amount of foggers and wait the recommended amount of time. Repeat again in a few weeks if needed. Most foggers/bug bombs work on most spiders and many are persistent over some time after application.
Also, you can't just look at the amount of food produced, but the amount produced vs waste, storage and transportation costs. Most things in the garden can stay ripe on the plant for a while and can be picked as needed.
Anecdotally, we were supplying about 80% of our fruit and veg needs on our own garden plot on our standard city residential lot with a family of 7. And we were literally giving tomatoes, citrus and zucchini away as fast as we could.
Very big bullet, much recoil. Very ouch. They're rough to shoot in a heavy rifle, there would be consequences shooting then out of a light pistol.
