ASPECTEK Electric Indoor Bug Zapper

Averaged from 1 derived from review text + 4 unscored
The verdict

The ASPECTEK HR292 is a 20W plug-in zapper with two UV bulbs and a 2,800-volt grid behind a mesh guard, sold for indoor and covered outdoor use. Bob Vila's bug zapper roundup, which tested six models, named it the best pick for indoors and found it performed as well as many outdoor units of similar design. Its complaints were the loud pop on each kill and a bright, utilitarian look that it said most people would not want in a bedroom.

Full review

Bob Vila's pick for indoors

Bob Vila tested six bug zappers during the height of bug season in the South, running each for a set period at night and judging it by the insect body count afterward. The Aspectek HR292-1 20W was its best-for-indoors pick.

The roundup reports that it performed as well as many outdoor models using similar black light and grid designs, attracting and dispatching bugs at a high rate. Bob Vila went as far as saying it seemed almost too effective for a typical indoor space already protected by window screens.

Noise and looks

The drawbacks Bob Vila lists are the ones that matter in a house. The unit emits a loud pop when it kills an insect, which the roundup calls a bit unsettling for indoor use, and it describes the look as bright and utilitarian. Its conclusion is that this is probably not something most people would want in their bedrooms.

Steve Jenkins, who reviewed an Aspectek indoor zapper of the same two-bulb, 2,800-volt design on his blog in 2015 (the post does not give a wattage or model number), made the same point: the zap did not bother him, but jumpier members of his family found it startling. He also switched it off at night because of the blue glow.

Setup, safety and cleaning

Bob Vila says it can sit on a countertop or be mounted to a wall with the included hanging chain. A sturdy mesh screen prevents people or pets from touching the electrified grid, and the removable, washable collection tray makes cleanup fast and easy.

Jenkins simply set his on a kitchen counter, found three dead flies in the tray within 45 minutes, and wrote that his fly problem was solved after a few days.

Where it fits

Bob Vila recommends it for a significant fly or mosquito problem in a home's main living area, and for a garage, screened-in porch or covered patio. It rates the unit for indoors or covered outdoor areas and about 1,000 square feet.

The Amazon listing describes the linked version as a 20W zapper with a 2,800-volt grid, for indoor and covered outdoor use, with two replacement bulbs in the box.

  • +Mesh screen guards against accidental contact with the grid, per Bob Vila
  • +Removable, washable tray makes cleanup fast, Bob Vila found
  • +Sits on a counter or hangs from the included chain
  • +Two replacement bulbs are included, per the Amazon listing

Watch-outs

  • −Loud pop on each kill, which Bob Vila called a bit unsettling indoors
  • −Bright black light and utilitarian look; Bob Vila would not put it in a bedroom
  • −Not for open outdoor use: Bob Vila lists it for indoors or covered outdoor areas only

How it compares

Bob Vila lists the ASPECTEK Electric Indoor Bug Zapper for indoors or covered outdoor areas with about 1,000 square feet of coverage, against 625 square feet for the Black+Decker BDPC941 Bug Zapper and up to 1 acre for the outdoor-only Flowtron BK-40D Electronic Insect Killer. Its 2,800-volt grid is half the 5,600 volts listed for the Flowtron and below the 4,200 volts on the GOOTOP Indoor and Outdoor Bug Zapper's listing. Bob Vila found it pops loudly on each kill, where the Black+Decker kills without an audible snap.

GOOTOP Indoor and Outdoor Bug Zapper
#1 · Top Pick

GOOTOP Indoor and Outdoor Bug Zapper

Bob Vila lists the GOOTOP Indoor and Outdoor Bug Zapper at up to 1/2 acre of coverage, between the 625 square feet of the Black+Decker BDPC941 Bug Zapper and the 1 acre claimed for the Flowtron BK-40D Electronic Insect Killer. Unlike the outdoor-only Flowtron it is also meant for indoor use. Its listing gives a 4,200-volt grid, against 2,800 volts for the ASPECTEK Electric Indoor Bug Zapper, and Bob Vila reports a zapping sound on each kill, where it found the Black+Decker kills without an audible snap.

Flowtron BK-40D Electronic Insect Killer
#2

Flowtron BK-40D Electronic Insect Killer

The Flowtron BK-40D Electronic Insect Killer is the only outdoor-only unit on this page and the only one Bob Vila scored in a standalone review. Bob Vila lists its coverage as up to 1 acre, against about 625 square feet for the Black+Decker BDPC941 Bug Zapper, and found the Flowtron far more effective in a heavily wooded yard but much louder and brighter than the near-silent Black+Decker. Its grid is listed at 5,600 volts, double the 2,800 volts of the ASPECTEK Electric Indoor Bug Zapper.

Black+Decker BDPC941 Bug Zapper
#4

Black+Decker BDPC941 Bug Zapper

Bob Vila lists the Black+Decker BDPC941 Bug Zapper at about 625 square feet of coverage, against up to 1 acre for the Flowtron BK-40D Electronic Insect Killer, and found it made less of a dent in a heavily wooded yard than brighter fluorescent units. In exchange it is quiet and dim where the Flowtron pops loudly and glows bright blue, and it can be used indoors, which the Flowtron cannot.
