I plugged my repeller in but haven't noticed a difference?

It's important that steps are taken to help the effectiveness of the product such as clearing up leftover food or rubbish that rodents will be attracted to and blocking entryways. The repeller is a training device and as such may take up to 28 days to break the visiting habits of the rodents. You should not use baited traps or poison baits at the same time as this will counteract the repel action.
