LED streetlights are killing 10% of moths in England

Well, it is actually 50% I don't have any idea why The Guardian used "Decimate." Don't Brits know what words mean?!

So, LED streetlights halve moths.

I am supposed to care about moths now? I never liked them before!

Of course, LED lights are more energy efficient than the old sodium lights, which reduced moth population by 40%.

The problem is the lights are bluer. Wait. LEDs can be any color and, as I understand it, colors outside of the visible spectrum.

So get LEDs with warmer colors!

They said there are blue light filters and then resumed claiming that LEDs were dangerous for moths.

Why didn't they just install blue light filters instead of complaining to us first?

They also said that female glowworms take 15 times as long to find a mate with streetlights.

You and me both, female glowworms.

Is crime good for female glowworms? What about car accidents? Streetlights should reduce both!

I feel like this article was the equivalent of saying "Maggots are down 20% since we cracked down on murder!"

Oh boy! My brother just asked to go to Sonic! Mom isn't up and I have a client in 16 minutes! Got to go!

I can't care about moths, and can't imagine a more boring story if I tried real hard.

LEDs can't be any color. They can be red, green, and blue (maybe a couple others?).

The appearance of white light is achieved by either combining RGB (less common), or using a phosphorus coating that emits white light when excited with blue light emitted by an LED. The latter is similar to how fluorescent lights work.

I say crank the blue and see if we can further decimate the moth population. Now if only it worked on mosquitos...

You can get to white in LEDs by a couple of processes. Rgb is one, uv and flourescent is #2, #3 is a blue/white doping compound which is what high power ones are made from. It has a uv spectrum component that not humans see.

Mosquitoes are heat seakers, down in the infarred with added Co2 detection.. Hit them with a propane burner and cow saliva.

Don't want to know how you collect cow saliva.

I imagine an apple placed just out of reach, and a trough to collect the excess excretions.

Allegedly bug zappers don't kill mosquitos and you are a bad person for looking into them. I hate mosquitos, but I don't want flies, moths, or anything else climbing on me when I am outside. We're not talking bald eagles. If a bug lands on me or tries to land on my food I will swat it, so if I want a bug zapper near me when I am outside then the dippy and baloney-filled hippies can do push-ups.

I'm not leaving it on unless I have food outside, but I guess the moral of the story is to always have food covered outside.

If it is not bad enough that bug zappers are evil and only evil people want them, they make bugs explode! Exploded bug parts can travel up to one mile [or something]!

Okay, once again I need to explain the inverse square law. If a one-gram bug gets spread over a one foot radius, that gram of exploded bug guts is spread out over 4π ≈12.56637 square feet.

If bug guts travel 8 feet then 1g of exploded bug guts are spread over 256π ≈804.24772 square feet.

Is that desirable? No, but neither is having bugs in your food, so cover it!

Obviously you would want a bug blast shield between a bug zapper and people, but since mosquitos aren't attracted to light, maybe a bug zapper with a human-scented candle instead of a fluorescent light?

What about a bacon candle?

I originally shared a 4-minute Hallmark video, but as someone commented, there was far too much talking (and laughing). The Hacksmith showed it in 60 seconds!

You just save a bunch of bacon grease, mix it with unscented candle wax, pour it into a jar, dangle a wick into it, and give it a couple hours of alone time. The Hacksmith melted votive candles and reused their wicks. Hallmark used a commercial one.

Some people use straight bacon grease, but someone pointed out that it melts more than candle wax, so it is more of a tip hazard.

The odd thing is that some people say it doesn't smell like bacon at all.

What?! Why would you do this then?! Someone said you are getting a cheap candle and not dumping bacon grease, but you can buy candles that size from Dollar Tree.

If it doesn't smell like bacon does it still attract mosquitos?!

Apparently if you want a turkey bacon candle your peers will laugh you to scorn. The thing is, turkey bacon may be healthier, but that is because they are leaner, which means that you need to cook more in order to get enough grease to make a candle.

But wait! There's more!

Everybody knows about the King of Random's bacon soap video:


He renders bacon, simmering an entire pound of chopped bacon on the stove for 8 hours. Then he mixes the rendered pork fat with water, puts it in the refrigerator for 8 hours, and scrapes off the impurities.

Another guy filtered it. He went through a couple coffee filters.

They seem to become saturated with fat.

You could also pour off the fat. There are measuring cups designed especially for that.

Whatever.

He got 70g of pork lard from 1lb of bacon.

That sounds like a lot of work to remove the 85% that is impurities.

According to La Quercia Tamworth Country Cured Bacon propaganda, normal bacon cooked normally loses over 55% of its weight, but how much of that is pure grease, and how much is impure?

What difference does it make?

Who cares if it doesn't smell like bacon and doesn't attract mosquitos?!

I don't know how they collected it, it was just an effeciency option on the propane powered skeeter cooker.

I had one which I bought while living in Pelotas. Not only it killed mosquitoes, it also brought to my attention some insects that I didn't even know they existed, as I didn't see those in Porto Alegre.

At F.O.B. Lindsey in Afghanistan, adjacent to Kandahar Airfield, on the same Afghan National Police base, they had some kind of insect trap. They seemed to work, the bugs didn't get out, but maybe they didn't want to.

They had some kind of food in there and the insects seemed to flourish. They were just trapped or maybe the food was too good to leave.

I guess they just ate until they ran out of food.

I hope they truly were trapped because unleashing thousands of hungry bugs from each trap would be inconvenient.

Specialized LED lights are “barely” more efficient than low pressure sodium

Low pressure sodium lights unlike high pressure doesn’t kill moths, turtles or other wildlife it also lasts as long as LED and should be cheaper up front and around the same effiency

Also less likely to kill your night vision while driving and less glare
