Make your space less inviting to pests.
RODAR® II helps repel rats, mice, bats, squirrels, fleas, roaches, and other unwanted pests with powerful ultrasonic sound — without poisons, bait, or traps to set.
Plug RODAR® II into a standard outlet, aim it toward the problem area, and let it run continuously. It is designed for enclosed indoor spaces such as kitchens, attics, basements, garages, cabins, campers, storage rooms, offices, and work areas where pests try to nest, feed, or enter.
Less welcoming to pests. More comfortable for you.

Explore crawling pestsHigh-frequency sound pests notice — without chemicals in the room.
RODAR® II emits ultrasonic sound in the 23–55 kHz range. The sound is designed to make protected areas uncomfortable for many pests while staying above the normal hearing range of people.
Ultrasound works best when the front of the unit has a clear path. Walls, closed doors, heavy furniture, cabinets, and packed storage can reduce coverage, so larger or divided spaces may need more than one unit.
Connect to a standard outlet in the space where pest activity is seen or expected.
Point the front of the unit toward open room space, pest travel paths, or likely entry areas.
Run RODAR® II continuously so the protected area stays less comfortable for pests.
Clean food sources, reduce clutter, and seal openings to make the space harder for pests to use.
Pest control electronics should be built like electronics.
Micron has manufactured RODAR® systems since 1992 and has been involved in the product’s design, manufacturing, marketing, order fulfillment, and support ever since. That history matters when a device is expected to run quietly, continuously, and reliably in real spaces.
Decades of product feedback help shape the instructions, packaging, placement guidance, and support.
As an electronics manufacturing services company, Micron brings process control and repeatable assembly to a consumer pest-control device.
RODAR® II is intended to stay plugged in around the clock, so reliability is part of the product’s value.
Plug in. Aim at activity. Leave it on.
Good placement helps RODAR® II do its job. Start near the problem area, give the sound a clear path, and keep the unit running continuously.
Choose the problem area.
Place or mount the unit in the kitchen, attic, basement, garage, storage room, cabin, camper, office, or other enclosed area where pest activity is seen or expected.
Aim the front clearly.
Point the speaker face toward droppings, nesting spots, entry points, or open space where pests travel. Avoid blocking it with boxes, curtains, furniture, or appliances.
Keep it working.
Leave RODAR® II plugged in 24/7. Sanitation, sealing, and clutter reduction help ultrasonic coverage work harder.
Make the space harder to enter, harder to live in, and harder to ignore.
RODAR® II is a repelling device. It works best as part of a practical pest-prevention plan: remove attractants, block access, and use continuous ultrasonic coverage where pests are active.
- ✓Clean away attractants.
Crumbs, spilled pet food, open trash, bird seed, and standing water give pests reasons to stay. - ✓Seal small openings.
Close gaps around pipes, vents, doors, foundations, and utility penetrations after pests have a route out. - ✓Keep the sound path open.
Ultrasonic sound needs open air. Add units for separated rooms or areas blocked by walls and heavy storage. - ✓Give the area time.
Pest pressure, nesting habits, food availability, and layout affect results. Keep the unit running while conditions improve.
One device. Many pest-prone spaces.
Use RODAR® II in enclosed indoor spaces where pests are active today, or where an ultrasonic barrier can help discourage new activity.
Reduce rodent pressure around food storage areas while cleaning up crumbs, sealing gaps, and removing easy food sources.
Aim ultrasonic coverage into open storage, rafters, corners, and entry areas where bats, squirrels, mice, and other pests can settle in.
Keep protected seasonal spaces less welcoming when they sit empty, especially when ultrasonic coverage is paired with sealing and sanitation.
Discourage pests. Improve the environment.
RODAR® II focuses on discouraging pests from staying in the treated area, while EnergAire® helps create a cleaner, healthier indoor environment that is less attractive to them in the first place. EnergAire® helps by reducing airborne organic matter, particles, and contaminant load.
RODAR® II
Creates a continuous ultrasonic environment designed to discourage unwanted pests from remaining in the treated area.
EnergAire®
Uses quiet, filter-free ionization to help reduce airborne organic matter, particles, and contaminant load.
Support both the pest problem and the space around it.
Address pest behavior.
RODAR® II helps make the treated area less comfortable for pests that can detect its ultrasonic output.
Support environmental quality.
EnergAire® helps reduce airborne organic matter and contaminant load in the surrounding room.
Remove the reasons pests stay.
Cleaning, moisture control, sealed food, reduced clutter, and closed entry points strengthen the overall approach.
RODAR® II and EnergAire® work independently. Pairing the products does not increase RODAR® II’s ultrasonic coverage; it adds a separate layer of environmental support.
A more complete approach for pest-prone indoor spaces.
Pests are influenced by more than one condition. RODAR® II focuses on discouraging them from staying, while EnergAire® helps support a cleaner indoor environment with less airborne organic matter and contaminant load.
Place RODAR® II near pest activity.
Aim the front panel across open air toward likely travel routes, entry areas, nesting zones, rafters, wall edges, or other signs of activity.
Give EnergAire® room to circulate air.
Place EnergAire® in an open area where airflow is not blocked by furniture, curtains, boxes, or tightly packed storage.
Run both products consistently while wiping surfaces, managing trash, cleaning spills, reducing moisture, securing food, and sealing pest entry points. EnergAire® supports the air; regular cleaning removes material that has already settled.

Helpful answers about ultrasonic pest control.
RODAR® II is simple to use, but placement and expectations matter. These answers help buyers choose the right setup before ordering.
What is RODAR® II?
RODAR® II is a plug-in ultrasonic pest repeller manufactured by Micron Corporation. It is designed for indoor and enclosed spaces where rats, mice, bats, squirrels, fleas, roaches, and other pests are active or likely to enter.
How does RODAR® II repel pests?
RODAR® II emits high-frequency ultrasonic sound. Many pests find the protected area unpleasant, which encourages them to move away from the sound source.
Does it use poison, bait, or traps?
No. RODAR® II does not use chemicals, bait, or traps. It is designed to repel pests rather than capture or kill them.
Where should RODAR® II be used?
Use it in enclosed spaces such as kitchens, attics, garages, basements, cabins, campers, offices, storage rooms, restaurants, farms, and similar areas where pests are active or likely to enter.
How many units are needed?
One unit can cover up to 3,000 square feet under favorable conditions. Walls, closed doors, partitions, heavy storage, and separate problem areas can reduce coverage and may require additional units.
Is RODAR® II safe for pets?
RODAR® II is intended for use around people and non-rodent pets such as cats and dogs. It should not be used near pet rodents such as hamsters, gerbils, rats, mice, or guinea pigs.
How long does it take to see results?
Results depend on infestation size, food availability, nesting behavior, room layout, and placement. Keep the unit on continuously while cleaning, sealing openings, and removing food and water sources.
Should RODAR® II be paired with EnergAire®?
RODAR® II can be used on its own. Pairing it with EnergAire® adds air-purification support for spaces where cleaner air, less stale odor, and non-chemical pest deterrence all matter.
Is RODAR® II backed by a guarantee?
RODAR® II is backed by a money-back guarantee. Review current purchase terms at checkout or contact Micron for details before ordering.
