How do I install and use the Mighty Ultrasonic Repeller?

Plug into a wall socket 20-50cm off the ground, clear of furniture or curtains. Switch on — indicator light confirms activation. Run 24/7 for maximum results.

What pests does it target?

Designed for mice and rats — cycling waves keep them unsettled.

Why is there an initial pest spike?

This is normal: ultrasonics disturb rodents, prompting more activity as they flee. They'll clear out soon.

Yes — it may irritate small pets like chihuahuas however (ie. rodent-sized animals). If you have any concerns, please keep an eye on your pet’s behaviour or switch to a lower mode. No toxins involved.

How long until results?

Pests may linger 1-2 weeks, then flee as waves disrupt them.

80-120 sqm in open spaces. Use more units if you have blockages e.g. walls / furniture.

20-40cm off floor, in unobstructed outlets.

They emit cycling high-frequency waves (15-70kHz) — silent to humans, irritating to rats, mice, cockroaches, spiders. Pests flee the discomfort. Plugs into standard 240V AU socket; covers 120 sqm open space (add additional units if you have walls/furniture and other obstructions).

Where should I use them?

Food + shelter hotspots: kitchens, pantries first. Then storage, laundries, garages, sheds — clear paths maximise wave reach.

Where to Place Your Repellers

Pests target food, shelter, warmth. Position repellers here for maximum impact:

Kitchen and pantry
Laundry and garage
Dining room and storage
Animal feed areas, sheds
Roof cavities and farm spaces

Pro tip: 20-50cm off ground, one per 100 sqm, no obstructions.

Maximise Effectiveness

Clear space around the repeller — no furniture blocking waves for full room penetration.

While the Mighty is designed specifically to repel mice, rats and other rodents, customers have also had success keeping away a range of other small creatures including bugs, ants, cockroaches, mosquitoes and spiders.

Note: Brief pest uptick is normal — they're fleeing. Activity drops soon after.

Plug In Pest Control

My order was received quickly which I was grateful for as I had seen a field mouse in my unit. Since using the units, I haven't seen any more mice, cockroaches and only 1 silverfish - its a little cool to be seeing other pests. My only problem is the pulsing light in the night - I have one of the units in my bedroom and I am used to a dark room so having a light pulsing is taking a bit of getting used to when I wake up in the night and wonder why the room is bright!! :) Very happy I brought this product as I don't like traps where I have to remove dead animals.

The mighty plug In

I brought this in a 3 pack a few weeks ago, very quick delivery, I have a 2 storey unit, so one up stairs and one downstairs, I certainly have noticed that I dont have ants no more, nor many flies, and I gather nothing else either, so I’m happy with this product.., the 3rd one I gave to my sister.
I have just purchase a packet of Gnat pads, shame it doesn’t work on them hahah..

great pest repeller

This little device is fabulous! I have not seen a cockcroach since installing it!
Very happy with my purchase.

Envrobug

Have found them very good, had ther last model and they worked as they should. These new model seem to being ther job they have only been up for a week and all the bugs seem to be slowing down.

Excellent product

I have been using a more expensive brand for years and have found Envirobug to be just as effective and also looks better in the wall socket. Thanks. Will certainly recommend
