Estate sales, yard sales, and antique shops were regular weekend destinations for my brother and me as kids. My parents, always on the hunt for period-appropriate decor for our Staten Island 19th-century house, made sure of it. Since then, I’ve had a love for home design and…read more

Unfortunately, mosquitoes love me. As a result, I usually spend my summer wearing long-sleeve shirts and swatting at the air around me. So when I heard about the Thermacell Patio Shield Mosquito Repeller, I took immediate notice. With up to 12 hours of coverage and a “zone of protection,” it’s just what I need to sit outside comfortably. Reviewers say the repellent even gets rid of mosquitoes in the woods and rural areas. 

And right now, it’s on sale for 33% off, bringing the price down from $74.97 (if purchased separately) to $39.98 – a deal that’s comparable to Amazon’s Prime Day discount.  If you’re new to QVC, you can get an extra $30 off your first order of $40 or more with code HELLO30 through July 10. Your bug-free summer starts now.

What Is the Thermacell Patio Shield Mosquito Repeller Duo?

The Thermacell Patio Shield Mosquito Repeller Duo is a must-have for outdoor gatherings. Just turn one on and within 15 minutes, you’ll have a mosquito-free coverage area of 15×15 feet. Here’s how it works: The butane cartridge inside heats up, and then the mat above diffuses a proprietary mosquito repellent. It’s scent-free, pet- and kid-friendly, and doesn’t require any sprays or lotions. Each cordless repeller is 3.25×6.25 inches and weighs just 6.5 ounces, so they’re easily portable, whether you’re at home or on vacation. 

Shoppers have called the Thermacell Patio Shield Mosquito Repeller a “game-changer” and recommend using it everywhere, from campsites to balconies. This set includes two repellers, six 12-hour butane cartridges, and 18 mosquito-repellent mats, and has been EPA reviewed. So, if you want to avoid a summer of scratching, take advantage of this major deal.

What QVC Shoppers Are Saying

Average Rating: 4.1 / 5

“After purchasing various types of Mosquito repellents, I finally found this Patio Shield from Thermacell. Easy-to-follow instructions, so once I set it up outdoors and waited approximately 15 minutes, the mosquitoes disappeared. I noticed it works better on less windy days. I use it near the pool or patio while barbecuing and at the park. It’s worth it!” —Just Kat

“The mosquitoes have been relentless this season … until I started up my patio Thermacell. This company has now earned my lifetime loyalty. This is the only product you need. Stop spraying yourself just to continue to get bitten. Start up your Thermacell, leave it outside for about 15 minutes, and then join it to enjoy a beautiful summer night with no bites.” —Carria

“This works so well that I sit it on my covered firepit. After a few minutes, skeeters that are hiding under the edge of the pit start leaving. Never even land on me — they just leave!! If you don’t have one — buy two!!” —Skeeters
