10 Best Fly Repellents

The Mortein NaturGard Multi-Insect Automatic Spray offers a convenient way to protect your home from flies, mosquitoes, and other common insects both indoors and outdoors. It uses a natural plant-based pyrethrin as its active ingredient, which is effective at killing a range of pests including ants, moths, fleas, and cockroaches. One of its strengths is the automatic spray feature that releases regular bursts of mist, ensuring continuous protection without needing frequent manual application. The fragrance-free formulation is a plus for people sensitive to strong smells.

Designed for both indoor and outdoor use, this spray covers a wider area than many basic sprays. Although the natural ingredient is generally safer than harsh chemicals, users should still follow safety instructions to avoid contact with skin or eyes. This automatic spray is suitable for those seeking an easy, hands-off approach to keeping multiple types of insects away, especially in spaces where strong fragrances are undesirable.

The Thermacell Backpacker Mosquito Repeller is a compact and lightweight device designed to protect an area of about 21 square meters from mosquitoes, making it a great choice for campers, hikers, and outdoor enthusiasts who want hassle-free protection. Instead of sprays or lotions, it uses a scent-free repellent mat heated by a small gas canister (not included), so you avoid chemicals like DEET and sprays that can be messy or smell strong. Each repellent mat lasts up to 4 hours and changes color when it's time to replace it, which is a handy feature.

The device starts working in about 15 minutes, creating a mosquito-free zone without bothering you or your pets. It’s easy to carry, weighing only 220 grams, and comes with a travel bag for convenience. However, you do need to have camping gas canisters to power it, which adds a small extra step. Also, while it covers a decent area, it may not fully protect larger groups or open spaces.

If you want a portable, chemical-free mosquito repellent for small outdoor areas and are okay with managing gas canisters and replacement mats, this product provides effective protection without unpleasant smells or sticky sprays.

Coming from a reputable Australian brand, it provides reliable defense against disease-carrying insects, making it a practical option for outdoor protection.

This product suits those looking for a straightforward, odourless repellent with long-lasting effects in a handy aerosol form.
