Gen X and Millenials don't share Boomers' obsession with green lawns, so it's a race against time, whether Boomers or lightning bugs will go extinct first

I thought lightning bugs were mostly from light pollution and deforesting? I live in the woods not near a major city, and every summer there's thousands of them still, thankfully.

This stopped working in the mid-Atlantic when invasive tiger mosquitoes arrived. They need like a bottle cap sized amount of water so even things like a flower can hold enough water for them to reproduce. We’re using scented lures which have the right salt + lipid combo to attract mosquitoes. It helps but I still wish Nathan Myrvold had seriously developed that “photonic fence” product.

I think the next best thing is an automatic turret that fires salt bullets or something, maybe AI. Hopefully it doesn't take an eye out, but if it took out like 1million mosquitoes for 1 eye, worth it?

I think you would run out of eyes before running out of mosquitos.

It is my hope that humans can ditch their love affair with pesticides. This is just one example of the unintended impact of pesticides. I have also found dying birds in my yard a few days after the neighbor sprayed their house perimeter for ants. No toxicology report but there was no sign of any physical damage.

Pesticides form the backbone of crop protection. Without them, we're looking at at least a 40% reduction in global yield, and much greater uncertainty in food supply chains (the oil shocks show how bad that can be). Pesticides per se are not the problem; synthetic broad-spectrum pesticides with many unintended effects are. They're often toxic to people and ecosystems, and resistance among pests and pathogens is increasing anyway, so their days are numbered to a degree. Biopesticides, which are generally safer and much more sustainable, offer a real solution to at least the safety issue.

I work on RNAi-based biopesticides (sprayed dsRNA) - non-GM, doesn't impact beneficial species, doesn't hang around in the environment, etc. Already ubiquitous in nature (and part of our diet). Peptide-based biopesticides are another approach that is going well. Both approaches are now commercialised by smaller players (e.g. for varroa mite control in bee hives by GreenLight), and not by the Bayer, Syngenta types.

Stop planting butterfly bushes! It’s a trap. Instead, plant milkweed. Support their entire lifecycle. The names of these plants ought to be changed.

You should only be planting native species whatever they are for your specific area.

The “butterfly bush” is native to China. Milkweed is native to North America.

Milkweed is the only one that can feed the Monarch at all stages of its life, from larva to caterpillar to butterfly. When people plant butterfly bushes, it “tricks” the butterfly (or at least crowds out better options) into laying eggs where the larvae will ultimately die of starvation.

I'll never forget my first week working housing demolition in the Japanese countryside a few years ago. We were outside tearing down an old house, when I saw what I thought were bats. In broad daylight. But they were moving slowly... and I could see their wings beating. Holy crap, those are butterflies. Huge, stunningly beautiful, butterflies. And not just one or two, but many of them. When I was able to get a bit cl…

This was common in America once. Around the 1900's, in "wild" places like Texas, you'll see references to clouds of butterflies, in memoirs and such.

I had a salesman come to our place saying that a neighbor had spiders, so their whole backyard was treated! I laughed and shut the door.

i had a salesman say he noticed i had a lot of spiders around outside. he asked who i currently use for pest control. i said, "the spiders." he excused himself and left.

maybe they don't make great decorations, but the spiders generally stay in their webs and don't bother me. i once watched one defeat a wasp twice its size. i might feel differently if we had any dangerous spiders around here (just black widows, and they stay in dark hidey holes), but i'm happy to trade a little space for their services.

Fuck it, everyone wear safety goggles outside and try not to make any jerky movements.

We had a really bad year of mosquitos and got one of the spraying services in. An hour later, monarch having a seizure on our porch. Oops. Never again.

The only things that work around here are the thermacell repellents (they have a little butane fire that evaporates stuff off a mesh pad). Their effect seems pretty localized in time and space, but I wonder what's in them, and how problematic it is.
