10 Best Fly Zappers 2026 in the United States

The Bug Zapper Outdoor by GOOTOP is designed to cover a generous area of up to 1/2 acre, making it suitable for use in various outdoor settings such as patios, gardens, and backyards. With a wattage of 15W and a powerful 4200V electric grid, it effectively attracts and eliminates a wide range of flying insects, including mosquitoes, flies, and wasps.

The zapper is lightweight and easy to hang, plus it starts working immediately upon plugging in, making it user-friendly. The construction is made of durable ABS plastic, ensuring longevity. One of its significant advantages is the ease of maintenance, as the dead insects fall into a tray that can be easily cleaned with the provided brush, and the bulb is replaceable when it becomes less effective.

Safety is also considered, as it provides a way to control insects without chemicals, making it safer for pets and humans. However, it is most effective when used at night or in the dark, which might limit its usability during the day. Additionally, while it is EPA registered, some users may still prefer non-electric pest control methods.

The ASPECTEK 20W Indoor Bug Zapper is a strong contender for anyone needing effective insect control indoors or in covered outdoor areas. It uses a 20-watt UV light with a wavelength of 365nm, which is particularly attractive to a variety of flying insects like mosquitoes, flies, moths, bees, and wasps. Its double-sided design allows insects to be attracted and zapped from all directions, covering a large area of up to 100 square meters (about 1,076 square feet), making it suitable for rooms, kitchens, offices, and even warehouses.

One big plus is its safety design: a protective mesh screen keeps you safe from accidental contact with the high-voltage 2800V electric grid inside. The metal and plastic construction gives it decent durability, while the removable tray at the bottom collects dead insects, making cleanup straightforward and hygienic. The product comes with two replacement bulbs, which is helpful since UV bulbs usually need changing after a while for continued effectiveness. Weighing about 4 pounds and sized at 15 by 10.6 inches, it’s portable enough to move between rooms.

It is mainly designed for indoor or sheltered use, so exposure to rain or water should be avoided. While it covers a large space, extremely large outdoor areas might require multiple units or a different solution. For those seeking a bug zapper that’s easy to maintain, safe for household use, and effective against a broad range of flying insects, the ASPECTEK 20W provides good value with reliable performance.

The Flowtron Electric Bug Zapper is designed for outdoor use and covers a large area of up to 2 acres, making it suitable for backyards, patios, and even farms. It uses a strong 120-watt power source and combines two methods to attract insects: ultraviolet (UV) black light and a special Octenol attractant that mimics animal breath to lure mosquitoes and other flying pests. This dual lure approach increases its effectiveness compared to simpler bug zappers. The zapper’s high-voltage grid delivers 5600 volts, which is more powerful than many competitors, helping to kill insects quickly and efficiently, including larger bugs.

The design prevents bugs from clogging the grid, so it requires less frequent cleaning. Its construction is rugged and weatherproof, made from polycarbonate that won’t rust or crack, which means it can handle all kinds of weather year-round. It is also CSA certified and made in the USA, ensuring it meets safety and quality standards. Maintenance is straightforward, with no need for messy sprays, tanks, or sticky traps—just occasional replacement of UV bulbs and Octenol cartridges.

This zapper is relatively heavy at 13 pounds and requires hanging installation, which might not be as convenient for some users. The Octenol cartridges need to be replaced monthly, adding a small ongoing cost. It is a strong choice for those seeking an effective, environmentally friendly way to control flying insects over a large outdoor space, but it may be more than necessary for smaller areas or casual use.
