ELECTRIC ROACH KILLER: DOES IT REALLY WORK?
Cockroaches / cockroj are some of the most stubborn pests you can face at home or in business. While baits, gels, sprays, and powders are common weapons, many people are now searching for modern, hassle-free solutions—like electric roach killers. But do these devices actually work, and are they worth your investment? Here’s everything you need to know.
What is an Electric Roach Killer?
An electric roach killer is a device designed to attract, trap, or kill cockroaches using electricity. These come in various forms:
-
Electric Traps:
Roaches are lured inside by food bait or light, then killed by a quick electric shock. -
Electronic Pest Repellers:
These plug-in devices emit ultrasonic or electromagnetic waves, claimed to repel cockroaches and other pests from your home. -
Bug Zappers:
More commonly used for flying insects, but some models attract and kill crawling insects like cockroaches.
How Does an Electric Roach Trap Work?
-
Attract:
Uses food bait, pheromones, or sometimes blue/purple LED lights to lure cockroaches inside. -
Kill:
Once inside, metal plates deliver a high-voltage shock, killing the cockroach instantly. -
Collect:
Dead insects fall into a tray or chamber for easy disposal.
Do Ultrasonic Repellers Work on Cockroaches?
Ultrasonic and electromagnetic pest repellers are widely advertised. The idea is that these sound waves disturb or drive away pests, including cockroaches / cockroj.
However, scientific studies and real-world evidence are mixed—many users see little to no effect on cockroach populations. Cockroaches tend to be very adaptable and may simply ignore the signals.
Advantages of Electric Roach Killers
-
No Chemicals: Safe for homes with kids and pets (when used as directed)
-
Reusable: Most traps can be emptied and reused many times

Limitations to Know
-
Coverage Area: Electric traps and zappers only affect roaches that physically enter the device.

-
Initial Cost: Usually more expensive upfront than gels or powders.
-
Regular Cleaning: Traps need to be emptied and cleaned for continued effectiveness.

Place electric traps where roaches are active—under the sink, behind appliances, in dark corners.
