Mouse and rat repellent without traps or poison
The PestRay Indoor Plug (2-pack) emits high-frequency sound that makes a room less comfortable for mice, rats and crawling insects — always on, silent to most people, nothing to trap or clean up. It works best as a deterrent layer on top of sealing entry gaps and tightening up food storage.

Common questions
How long does it take to get rid of mice without traps or poison?
Most people see activity drop within one to three weeks once entry points are sealed and food and water are removed. Deterrents can speed the sense of relief in occupied rooms, but the lasting change comes from exclusion and sanitation, so results build gradually rather than overnight. Established infestations take longer.
Does peppermint oil really keep mice away?
It can make an area modestly less inviting, especially in small enclosed spaces, but the effect is mild and fades as the oil evaporates, so it needs refreshing every few days. Treat it as a supplement to sealing gaps and removing food, never as a standalone solution. On its own it will not clear an active problem.
Do ultrasonic repellers work on mice?
They can help in open rooms as one layer of a larger plan, but be realistic: ultrasound does not pass through walls or furniture, and mice can habituate to a constant tone over time. Use a unit like the PestRay indoor plug-in 2-pack alongside exclusion and sanitation, not as a guaranteed cure by itself.
PestRay devices are humane deterrents, not pesticides, part of an integrated approach, not a guaranteed solution. Results vary by placement, local wildlife and how established the problem is.
