This is the question. Like THE question. Every single consultation I do in the East Valley, somebody asks it. "Sam, if I put all these lights on my house am I basically ringing the dinner bell for every scorpion in the zip code?" And I get it. If you've ever done the blacklight walk around your yard at night — and if you live in Gilbert or Mesa you probably have — you know these things are everywhere. So it's a legit concern.
But here's what's actually going on. Scorpions themselves? They don't care about your lights. At all. They're nocturnal hunters and they actually prefer the dark. What DOES care about your lights is the stuff scorpions eat. Moths, crickets, beetles — those guys are obsessed with light. Especially bright white and blue-toned light. So if you've got a big cool-white floodlight on the back of your house, what you've basically done is open a 24/7 bug buffet. And the scorpions are just gonna post up in the shadows nearby and wait for dinner to come to them. You didn't attract the scorpions directly. You attracted their food and they followed.
This is where the color temperature thing becomes a real practical decision and not just an aesthetic one. Because Gemstone Lights are smart LEDs you can shift them to a really warm amber-toned white. We're talking down in that 2800K range. Insects are significantly less attracted to those warmer yellow and orange wavelengths — it's been studied pretty extensively actually. So you're basically changing the signal from "hey bugs, party over here" to just... nothing. They don't register it the same way. Fewer bugs on your walls means fewer scorpions hanging around waiting to eat those bugs. You're breaking the food chain right at your roofline.
Where you put the lights matters a ton too and this is something I don't think people consider enough. How many houses have you seen with a big bright light mounted right next to the back door? Or right above a window? All you're doing is drawing every bug in the yard — and every scorpion following those bugs — directly to your entry points. That's literally the worst spot for them. Gemstone Lights sit up on the roofline, in the eaves. The light is coming from up high, away from ground level where bark scorpions are actually crawling around. You're keeping that whole attraction zone away from your doors and your foundation and the cracks where they squeeze inside.
The other thing — and I bring this up because people don't think about it this way — a well-lit yard actually makes it harder for scorpions to do their thing. They love hiding in dark cool spots. Under rocks, in woodpiles, in those little gaps between pavers. When you've got consistent layered lighting across the yard you're eliminating a lot of those pitch-black hiding spots. And selfishly? You can actually see the ground when you're taking the trash out at 9 PM. Which in Arizona is not a small thing. I'd rather see the scorpion from ten feet away than step on it in flip-flops.
The dimming feature is kind of your secret weapon here and I don't think enough people use it for this purpose. You do not need your lights at full brightness all night. Drop them to 20 or 30 percent. That's plenty of light for safety, it still looks great, but you're way below that threshold where you're acting as a beacon for every moth in the neighborhood. It's a subtle move but it works. You're working with the desert instead of fighting it.
There's a nerdy technical detail I want to throw in because it actually matters out here. Cheap LED lights — the ones from Amazon or whatever — a lot of them flicker at a frequency that you and I can't see but insects absolutely can. That rapid flickering is like a magnet for certain bugs. Gemstone uses high-quality drivers that put out a completely steady current. No flicker. It's better for your eyes, better if you've got security cameras, and way less interesting to the bug population. It's one of those invisible engineering things that you'd never know about until someone tells you but it makes a real difference when you're living in scorpion country.
Oh and one fun trick before I wrap this up. Some people ask me about putting blacklights everywhere since scorpions glow under UV. I mean... I wouldn't recommend that as your daily lighting setup. Your house would look insane.But what you CAN do with the Gemstone app is flip over to a blue-toned light whenever you want to do a quick scorpion check. Hit the blue, walk the perimeter, see if anything lights up on the stucco. We've done it at our own house and it's honestly kind of wild what you find. Then just switch back to your warm whites and call it a night. Day to day though? Stick with that warm amber tone. Bugs don't care about it, scorpions go hunt somewhere else, and your house still looks like the best one on the street. You're always gonna share the desert with some gnarly critters out here — that's just the deal. But at least with smart lighting you get to set the terms a little bit.
