My old porch used to have a stable population of little blue jumping spiders when I was younger. Most spiders freak me out but jumping spiders have small and stout enough proportions to be cute. Insects teach kids a lot about ecosystems directly through observation. Daddy long legs (american variant) would get red parasitic mites on them. Jumping spiders would eat the mites when they didn't have a host and praying mantises would eat the jumping spiders and the daddy long legs. There was a carpenter bee nest we let live in the roof too. Carpenter bees are very beneficial insects to have around. Their nests only ever grow to have a couple females and a single male at a time and is no larger than a large sharpie marker generally. The male, which is stingerless and harmless to humans, but larger than a bumblebee will buzz around and knock any other flying insects out of the sky with his body that dare to get within 10-15 feet of the nest. I don't know if carpenter bees just aren't aggressive towards people or if this nest was just very used to us, but they never bothered us or tried to fly through the door. It was great. The neighbors used to get harassed by yellow jackets in the summer but not us. Anytime they came near the porch the carpenter bee would knock them unconscious mid flight. We'd find dead yellow jackets on the ground all the time and it was a sight to watch happen through the screen door. Even European Hornets would steer clear of our porch on the rare occasion we'd see one around.
Example of how benign carpenter bee nests can be even if they're built into the side of your house. Those bees were there for around a decade before my family sprayed a monstrous amount of pesticides to kill the invasive stinkbug infestation that ballooned into the 10s of thousands in the early 2010s. After all that dust settled the ecosystem started to recover. Eventually wheel bugs, these huge 2+ inch long assassin bugs moved in and started eating the stink bugs. Thankfully wheel bugs don't like coming inside and are very shy around people, because they are scary bastards and do bite when frightened.
