10 Best Strong Mosquito Repellent 2025 in the United States

The Thermacell Patio Shield E55 is an effective mosquito repellent designed to create a 20-foot protection zone. This innovative device takes just 15 minutes to provide maximum protection, making it ideal for use around patios, poolsides, and backyards. It runs on a rechargeable battery that lasts for 5.5 hours, which adds to its convenience and portability. The product comes with a 12-hour repellent refill and a USB charging cable, ensuring you have everything you need to get started right away.

One of the key strengths of the Thermacell E55 is that it repels mosquitoes without the need for DEET sprays or lotions, making it a cleaner and more convenient alternative. Additionally, it has been independently tested and approved by the EPA for safety and effectiveness, which provides assurance in its reliability. The repellent is free of scent, smoke, and flames, making it comfortable to use and suitable for people with skin sensitivities.

However, there are some drawbacks to consider. The protection zone is limited to 20 feet, which may not be sufficient for larger outdoor areas. The battery life, while decent, may require frequent recharging during extended use. Additionally, the initial purchase includes only one 12-hour refill, so additional refills will be necessary soon if used frequently. Despite these minor issues, the Thermacell Patio Shield E55 is a solid choice for those seeking a portable and effective mosquito repellent for small to medium-sized outdoor spaces.

The Repel 100 Insect Repellent is a robust choice for those needing strong protection against mosquitoes and other biting insects. With an active ingredient concentration of 98.11% DEET, it's formulated for severe insect conditions, making it extremely effective in highly infested areas. The high DEET concentration ensures long-lasting protection, providing up to 10 hours of defense against mosquitoes, ticks, gnats, biting flies, chiggers, and fleas, which is excellent for outdoor activities and adventures.

The product comes in a convenient 1-ounce travel-size pump spray, perfect for easy storage and portability. Being unscented is a plus for those sensitive to strong smells. Its high DEET concentration might not be suitable for those with sensitive skin, and it can be harsh if not applied correctly.

For those who prioritize long-lasting and powerful insect repellent, especially in areas with a high risk of insect-borne diseases, this product is a solid option. However, users should be cautious regarding potential skin sensitivity and follow application instructions to avoid any adverse effects.

The Sawyer Products SP565 Premium Insect Repellent uses 20% Picaridin as its active ingredient, which is known for being effective against a variety of pests. In terms of concentration, 20% is a strong formulation that offers good protection. The product comes in a lotion form and is designed to be non-greasy, fragrance-free, and odorless, making it comfortable to wear and unlikely to irritate the skin. This could be particularly beneficial for families and individuals with sensitive skin who are looking for a hassle-free application.

It dries quickly and is safe to use on various materials such as clothing, backpacks, and even on synthetic coatings, ensuring it won't damage your accessories or gear. The protection duration is impressive, offering up to 14 hours against mosquitoes and ticks, and up to 8 hours against flies, gnats, and chiggers, making it a reliable choice for long outdoor activities like camping, hiking, or even backyard barbecues.

Although the product is fragrance-free and comfortable, some users might miss a pleasant scent that other repellents might offer. Additionally, the 1-quart size may be bulky for some users, making it less convenient for those who need a more portable solution. Despite these minor drawbacks, the Sawyer Products SP565 is recommended for its effectiveness and family-friendly attributes, especially for those who prefer a strong, scent-free mosquito repellent that does not harm their belongings.
