Firsthand Experience: To Thermacell or Not to Thermacell? That is the Question

The mosquito problem in our backyard was so severe that my family and I couldn’t enjoy spending time there without protective clothing and applying head-to-toe mosquito repellent. Interestingly, one day both my mom and I came home with the same solution: the Thermacell Patio Shield Mosquito Repeller.

We both looked at each other and laughed, knowing great minds think alike. While I had purchased only one unit, my mom bought five, indicating her confidence in the product. I paid little attention to the instructions, while my mom took the time read the directions meticulously.

As it turned out, her approach was the right one. Her unit worked perfectly and glowed with an indicator light, while I thought mine was malfunctioning. It took me a while to realize that I had missed the most crucial instruction – to twist the bottom to start the unit working. She had to demonstrate.

Once back in the yard, we learned placement was key. We placed the six units in a circle formation, each about seven feet apart since the range has a diameter of 15 feet. We sat within the circle, and magically, we didn’t have one mosquito bite. So, to answer the question, it is definitely better to Thermacell than not to Thermacell.

7. Best Budget Option – PIC Mosquito Repelling Coils

PIC Mosquito Repelling Coils

For those seeking a budget-friendly option to ward off pesky mosquitoes, look no further than PIC Mosquito Repelling Coils. These coils offer a simple yet effective solution that has stood the test of time, allowing you to enjoy outdoor activities without breaking the bank.

How do they work? Shaped like spirals, they are suspended in the air and burned at the outer end, releasing a slow and steady mosquito-repellent smoke. 

To maximize their effectiveness, it’s important to use PIC Mosquito Repelling Coils in areas with minimal breeze. When there is little air movement, the smoke emitted by the burning coil can linger in the immediate vicinity, creating a protective shield against mosquitoes. 

Warning: Mosquito coils should not be used in closed rooms or confined spaces. When concentrated in an enclosed area, the smoke released by the burning coil can irritate the eyes, nostrils, and respiratory system. Furthermore, it’s essential to avoid directly inhaling the smoke produced by the coils. 

Specifications:

  • Type: Mosquito Coil
  • Scent: Citronella
  • Active ingredient: Pyrethrins
  • Duration: 5 to 7 hours per coil
  • Coverage: 10 feet

Pros:

  • Coils are cost-effective
  • Long-lasting protection against mosquitoes
  • No need for fuel cartridges, outlets, repellent mats
  • Lightweight and portable

Cons:

  • Produces smoke that can pose health risks
  • Not unscented
  • Limited coverage area

Mosquito Guard Mosquito Repellent Incense Sticks

When it comes to finding a wallet-friendly and natural mosquito repellent, the Mosquito Guard Mosquito Repellent Incense Sticks are among the best options. This mosquito incense uses only essential oils to repel mosquitoes, which means no harsh chemicals or synthetic additives are in the formulation. 

In addition, this plant-based product can create a mosquito-free zone of approximately 12 to 15 feet where you can kick back, relax, and enjoy your outdoor activities. Just light up a stick, let the soothing aroma of essential oils surround you, and let the mosquitoes know they’re not welcome in your space.

However, it’s worth mentioning that these incense sticks have a burn time of around 45 minutes, and that time might be even shorter if there’s a bit of a breeze. So, be sure to stock up on enough sticks to keep the protection going. 

Specifications:

  • Type: Incense

Buyer’s Guide

With a plethora of mosquito-repellent devices available on the market, it can be overwhelming to choose the one that best suits your needs. That’s why this comprehensive buyer’s guide can help you make an informed choice and find the mosquito-repellent device that ticks all the right boxes for you.

Rechargeable vs. Fuel-Powered

When considering Thermacell mosquito repellent devices, you’ll encounter both rechargeable and fuel-powered options. Each type has its own advantages and considerations, allowing you to choose the option that best aligns with your specific requirements. 

  • Practicality: You don’t need to worry about charging batteries with fuel-powered devices. Instead, you can simply replace the fuel cartridge and repellent mats as needed. This makes them reliable companions in remote areas where electricity may not be readily available.
  • Affordability: Fuel-powered devices have a lower initial price compared to rechargeable ones. However, factoring in the cost of fuel cartridges and repellent mats, it turns out that even though rechargeable devices and their refills have a higher cost upfront, they’re a better deal in the long run (we did the math!).
  • Coverage: Rechargeable Thermacell devices, such as the E90 Mosquito Repellent, often provide extended coverage, creating a larger mosquito-free zone, especially when compared to fuel-powered devices (excluding specific cases like the Thermacell Mosquito Repellent Perimeter System).
  • Constant protection: One notable benefit of rechargeable devices is their ability to function while charging. This means you won’t be left without mosquito protection, even if the device needs a power boost. 

Ultimately, the choice between rechargeable and fuel-powered Thermacells depends on your specific needs and preferences. If you prioritize practicality and affordability, fuel-powered devices may be the way to go. On the other hand, if extended coverage and long-term cost-effectiveness are important to you, rechargeable devices offer a compelling option.

Coverage

If you’re someone seeking a large area of protection, paying attention to coverage is essential. Let’s explore how different devices offer varying coverage ranges and the factors to consider when evaluating their performance.

  • Thermacell devices are known for their reliable mosquito-repelling capabilities. Most devices provide a radius of protection ranging from 15 to 20 feet, creating a sizable mosquito-free zone around you. 
  • For those requiring protection over a significantly larger area, Thermacell also offers the Mosquito Repellent Perimeter System. This system can safeguard an area of 450 square feet or more, making it an ideal choice for large yards or when hosting large outdoor events.
  • Mosquito coils and incense provide a more localized coverage range. These compact devices typically protect an area of around 10 to 12 feet, creating a smaller bubble of mosquito-free space. 

Regardless of the device you choose, it’s important to remember that environmental factors can influence the protection zone. Factors such as wind speed and direction can impact the distribution of mosquito-repelling substances or smoke. 

Active Ingredient

It’s important to note that some mosquito repellent devices contain active ingredients such as metofluthrin and allethrin, which can be toxic to honeybees and other beneficial insects. Pyrethrins, found in our budget option, are also toxic to honeybees. These pesticides, while effective against mosquitoes, can pose risks to the delicate balance of our ecosystem.

To safeguard these vital pollinators and other beneficial insects, it’s crucial to focus on preventing mosquito breeding within our homes and surroundings. By eliminating standing water sources and using larvicides in ponds, we can create a safer environment for bees and other beneficial insects while still enjoying a mosquito-free outdoor experience.

Duration

The duration of protection is also a crucial factor to consider since the length of time a device can effectively repel mosquitoes directly impacts your outdoor experience. 

Thermacell’s fuel-powered devices typically offer up to 4 hours of protection before requiring a change of repellent mats. Rechargeable Thermacell devices, on the other hand, offer protection for as long as the battery lasts. Depending on the specific model, the battery life can range from 5 to 9 hours.

Mosquito coils and incense provide protection that is directly tied to their burn time. Mosquito coils typically burn for 4 to 6 hours, creating a mosquito-free environment throughout that duration. On the other hand, incense usually burns for about an hour, offering a shorter but still noticeable window of mosquito protection.

Warranty

Thermacell devices come with an automatic warranty that provides coverage for a specific duration, typically ranging from 1 to 2 years. This warranty ensures that your device is protected against defects in materials and workmanship, offering peace of mind and assurance of quality.

To further enhance the warranty coverage for your device, Thermacell provides the opportunity for 1 year of extended protection through product registration. By registering your device, you can extend the warranty beyond the initial automatic coverage period.

FAQ About Mosquito-Repellent Devices

Does Ultrasonic Insect Repellent Work?

No, ultrasonic insect-repellent devices do not work. They claim to emit high-frequency sounds that are supposed to repel mosquitoes and other insects, but numerous scientific studies have been conducted to evaluate their efficacy with no luck. The results consistently indicate that these devices do not provide significant mosquito repellency or protection against other insects.

What are Mosquito Dunks?

Mosquito dunks are a type of mosquito control product. They are donut-shaped larvicides that work by releasing a naturally occurring bacterium called Bacillus thuringiensis subsp. israelensis (Bti) into the water. This bacterium specifically targets and kills mosquito larvae, preventing them from developing into biting adult mosquitoes.

By utilizing mosquito dunks in areas of standing water, such as ponds and bird baths, you can proactively prevent the emergence of mosquito populations. This targeted approach helps to reduce the overall mosquito population in your surroundings and protect you and your family against diseases like the West Nile virus and Zika. 

What is the Most Effective Repellent for Mosquitoes?

When it comes to finding effective mosquito repellents, DEET takes the spot as the best mosquito repellent on the market. This active ingredient has been widely studied and proven to be highly effective in repelling mosquitoes. 

However, if you want to go DEET-free with the best natural repellents, consider other EPA-registered bug sprays containing picaridin, oil of lemon eucalyptus, or IR3535.

Calling in for Help

The world of mosquito-repellent devices offers a gateway to a bug-free paradise where you can fully indulge in the wonders of the great outdoors. 

But let’s face it: Sometimes, the battle against mosquitoes can escalate into an all-out war, especially if they’ve decided to turn your yard into their own buzzing kingdom. In such dire situations, it’s time to call for reinforcements. Pest Gnome connects you to the best pest control experts in your area to evaluate and treat your property.
