This is by FAR the BEST mosquito zapper we have ever had. It works so well we purchased 3 more for our more than 2 acres.

Watch it Work
A sensor turns it on at dusk and off at dawn. Nothing to plug in, empty, or babysit.

How GroundGuard Actually Works
Check an old hanging zapper and you'll find a tray full of moths — while your ankles are still covered in bites. So you figure zappers just don't work on mosquitoes. And you're right, but not for the reason you think.
Mosquitoes are weak flyers — barely 1 mph, grounded by the slightest breeze — so they hunt low, within two feet of the ground. And it's your feet they're after: they target the bacteria down there, and the scent is like catnip to them. That's why most of your bites land on your legs and ankles.
A zapper up in the air never had a chance. GroundGuard stands right in the mosquito flight path — the bugs that used to feast on you fly straight into it instead.
The amount of bugs this thing has in it every morning is amazing. We can actually enjoy the outdoors at night now! Charges great and lasts all night! You can hear it zapping the entire time. I loved it so much I got another one for the other side of the yard!
This zapper started clearing our patio the moment I plugged it in. The 365nm light immediately caused a swarm of bugs from all walks of bugdome to congregate around their new shrine to glorious bug doom. After a few nights, there was a noticeable reduction in the mosquitos and we were able to spend time out after the sun dropped.
I was skeptical at first, but after using it for the month of June I am a BELIEVER!! This thing has saved all of our cookouts from mosquito invasion. It will draw flies, mosquitos, and gnats away from you and your guests and keep them occupied. Easy to use, easy to clean.
I absolutely love this thing. Over the summer, the kids and I just watched thousands of bugs get zapped every night. We finally got our porch back from the bugs!
I was VERY hesitant about getting this zapper, worried that it wouldn't work. Well, I was wrong. We normally have a lot of mosquitos out on our patio, that sometimes make it impossible to sit outside. The very first time I plugged it in, within a few minutes, we were startled by a zap. It works super fast.
We do a lot of dinners outside in the summer, and occasionally we do family time when the sun starts going down. This has been a game changer. It keeps everything away from us. I actually bring it onto my front porch when we aren't using it in the back. I've even brought it in the kitchen for a day because flies got in. The battery lasts a decent time. I've never had it run out on me yet.
I live in a marshy area and have a pond out back. I get so many mosquito bites that I don't even want to be outside. I go out every morning and clean out probably a tbsp worth of dead mosquitoes. My husband likes that it doesn't kill off all the moths since they are bigger. I am just happy I am not getting bit any more!! It doesn't even need direct sunlight to charge as I have a lot of trees.
I was initially a bit skeptical about how well a solar-powered unit would perform, but it has completely exceeded my expectations. The battery life is phenomenal. It charges fully during the day, even on partially cloudy days, and it consistently runs strong all night long. Every morning, I see the evidence of its work — a pile of zapped flies, mosquitoes, and moths.
I found a way to control mosquitos on my deck. I love it so much that I ordered another one for my son who lives in Florida. In fact, I am thinking of getting another one for my daughter in Philly. If you are in need of mosquito control, this is a must.

What Customers Ask Before Their First Order
How much area does it cover?
+
One Sentinel covers up to 2,100 sq ft — plenty for most patios, decks, or pool areas.
- 1 Sentinel — up to 2,100 sq ft
- 2 Sentinels — up to 4,200 sq ft
- 3 Sentinels — up to 6,300 sq ft
Most customers grab two — one for the patio, one further out in the yard — to cover the whole space with no gaps (and save $149.95). Bigger property? Three wraps it in a perimeter so nothing gets through.
What bugs does it kill?
+
GroundGuard Sentinel eliminates all the bugs that ruin your outdoor time
- Mosquitoes
- Gnats & no-see-ums
- Flies
- Wasps & hornets
- Moths
- Other flying insects
No sprays. No candles. No swatting.
Does it work during the day too?
+
The UV light is most effective after dark when it's visible to insects. During daylight, bugs are less attracted to UV light. GroundGuard is designed for evening and nighttime protection, which is when mosquitoes are most active.
Is it even strong enough if it’s solar-powered?
+
Yes. The panel recharges the built-in battery by day, and at night the zapper runs off that stored power through a 4,500V grid — enough to drop mosquitoes, flies, moths and the rest on contact. If your yard's shaded or you hit a cloudy stretch, every unit includes a USB-C cable to top it off, so it never depends on perfect sun.
How long does it run on a charge?
+
A full charge runs it about 8-10 hours — dusk straight through to early morning. The light sensor flips it on at dusk and off at dawn, so it only draws power when it's actually dark. No switches, no timers, no babysitting.
Is it loud? Will it buzz all night?
+
No constant hum. You'll hear a faint click each time it catches a bug, but there's no buzzing bulb or motor. Staked a few feet out in the yard, most owners stop noticing it after the first night.
Can I leave it outside in the rain?
+
Yes — it's built to live outside through rain and storms; the housing is weather-sealed. Most owners bring it in over the winter off-season to preserve the battery, but it handles the elements all season while it's out.
Does it need cleaning?
+
Barely. There's no tray to empty — caught bugs fall away on their own. When the grid starts looking gunked up, just hose it off and you're done.
I'll probably come back and order later.
+
Most customers say that too. Then mosquito season peaks and they wish they'd started sooner. Every night without GroundGuard is another evening spent inside or covered in bites. Our 60-day guarantee means there's zero risk in starting now — but there's a real cost in waiting.
