Bonide Repels-All does list mice as one of its target animals, and the product can deter mice from treated outdoor areas. But its effectiveness is limited and tends to fade over time as mice grow accustomed to the scent. If you’re dealing with an active mouse problem, especially indoors, Repels-All is unlikely to solve it on its own.
What Repels-All Actually Contains
The active ingredients are putrescent (rotten) whole egg solids at 2.52%, cloves at 0.12%, and garlic oil at 0.06%. The remaining 97.3% is inert ingredients including fish meal, fish oil, meat meal, urea, vinegar, and wintergreen oil. The idea is to overwhelm a mouse’s sensitive nose with a cocktail of strong, unpleasant smells. Mice rely heavily on scent to navigate and find food, so a concentrated blast of rotting eggs and garlic can make an area unappealing enough that they avoid it, at least temporarily.
Where You Can and Can’t Use It
Repels-All is labeled for outdoor use only. This is a critical limitation for most people searching this question, because mice are typically a problem inside the house, not outside. You can apply it around homes, gardens, garbage cans, barns, woodpiles, sheds, decks, patios, and similar outdoor spaces. The label also specifically mentions treating bulbs and seeds before planting to protect them from mice, moles, and voles: spray them thoroughly until wet, let them dry, then plant.
The product is considered safe for areas where children and pets play, though the smell is noticeably strong when first applied.
How Long the Protection Lasts
The manufacturer claims protection for up to two months after the product dries. Once dry, normal rain showers won’t wash it off, though heavy or prolonged rain can reduce its effectiveness. For best results, apply at least six hours before expected rainfall and when the temperature is between 35°F and 85°F. You’ll likely need to reapply sooner than two months in practice, especially in areas with heavy moisture or high foot traffic.
Why Scent Repellents Have Limits
Here’s the honest picture: scent-based repellents like Repels-All may work initially, but rodents eventually get used to them. A guide from British Columbia’s government on integrated pest management puts it plainly: repellents, whether odor-based sprays or ultrasonic devices, lose their deterrent effect over time. Mice are adaptable animals. If food, water, or shelter is available in a treated area, they’ll push through the discomfort once the smell becomes familiar.
This doesn’t mean the product is useless. It can serve as a short-term deterrent for outdoor areas, particularly for protecting garden beds, bulbs, and seed plantings. Where it falls short is as a standalone solution for a mouse infestation. If mice are already living in or around your home, spraying a perimeter repellent won’t remove them or keep them out permanently.
What Actually Works for Mouse Control
The most effective long-term approach to mice combines three steps: exclusion, sanitation, and trapping. Exclusion means sealing the entry points mice use to get into your home. Mice can squeeze through gaps as small as a dime, so you’re looking at sealing cracks in foundations, gaps around pipes and utility lines, spaces under doors, and openings around vents. Steel wool stuffed into small gaps works well because mice can’t chew through it easily.
Sanitation means removing what attracts them in the first place. Store food in sealed containers, clean up crumbs and spills promptly, keep garbage in tightly closed bins, and eliminate water sources like leaky pipes or pet water bowls left out overnight. Without food and water, your home becomes far less appealing regardless of what repellent you spray outside.
Once you’ve sealed entry points and cleaned up attractants, snap traps are the most effective way to remove mice that are already present. They kill quickly and don’t rely on the mouse choosing to avoid an area. Place them along walls and in corners where you’ve noticed droppings or gnaw marks, since mice tend to travel along edges rather than through open spaces. Trapping or baiting alone won’t solve the problem long-term if mice can still get in and still find food, which is why exclusion and sanitation come first.
When Repels-All Makes Sense
Repels-All is best suited as one layer of an outdoor prevention strategy, not as your primary mouse control method. If you want to discourage mice from digging up freshly planted bulbs, nesting in a woodpile, or hanging around a garden shed, it can help for a few weeks at a time with regular reapplication. Pair it with removing debris, trimming vegetation away from your home’s foundation, and sealing any entry points into structures.
For an indoor mouse problem, skip the repellent and go straight to exclusion and traps. No outdoor spray will fix what’s happening inside your walls.
