We have tried our product at home and even built a maze to to watch the reaction of mice with peppermint oil. It's clear to us that mice avoid it. They typically come up to it, get too close and get overwhelmed, and then scurry back the direction that they came. Then they start grooming themselves, literally appearing to be rubbing their eyes. This is corroborated by our own experience in our own houses, where the product works for us. Our customer satisfaction is also very high. We've sold over 25,000 mouse balls and so far we have had only a few of our customers tell us they believe it didn't work for them. When we talk to them, we sometimes find that it was really a matter of not using them properly. It clearly works best preventatively, before they've found food in your house. If they've already found food, they will search harder and even create new ways to get in. .


There could be a number of reasons for this. One could be that they are selling conventional pest control services. The other could be that people have experience using the wrong kind of peppermint oil. There are different concentrations, different varieties, and you can try to extract the oil multiple times (first press, second press etc.), and they are not all the same in effectiveness. Then there's how you use it. It does not have extended range. You need a relatively confined space that the mice must go through, like an entry point, or an enclosed space (like a cabinet). So there can be many factors that people don't realize. You could also have airflow issues, where there is a lot of airflow bringing fresh air around the unit and drawing away the peppermint oil vapor. Finally, people might simply not be using enough. A couple drops on a cotton ball will dry up quickly and become ineffective. That's the whole point of our product, that it has a reservoir to provide a continuous supply of the right kind of peppermint oil to maximize effectiveness for a really long time (six months or more). So again, you have to look at the situation a little carefully and think about it a little when using peppermint oil. If you use our product in particular, and deploy it sensibly, it can be very effective.



The units prevent and repel mice by assaulting their incredibly acute senses. Peppermint oil, if it's the right kind, irritates their eyes and noses. (We work with it and completely agree so we have to be very careful with this stuff). From a distance they may find it attractive, but then when they get too close, they get overwhelmed (most probably in their eyes). Then they learn to avoid that smell, even from a distance. Depending on what you read, it's estimated that mice have a sense of smell that hundreds of times more sensitive than ours, so a weak peppermint smell to us can be overwhelming to them, which is what you want. Since they find it irritating, you can set up a perimeter by placing units near points of entry to your house (gaps around doors, behind cabinets or where pipes come in for example) to discourage mice from coming into your house, room, pantry etc. Also, you can place units placed in areas where there is evidence of mouse activity, such as in drawers or cabinets, and it will discourage mice from returning. This is most successful if it's preventative. In this case, the mice are exploring around the outside of your house, then they come across these entry points and find it irritating to enter. Since they are outside, they will have many other choices and options of where to explore so they just move on to try someplace else. Unfortunately, your neighbors might not be happy about this.



We have had customers try our devices to keep chipmunks and/or squirrels out of enclosed spaces and reported that it worked. We have honestly had limited experience with this. We do have considerable interest from people around a local lake that want to keep squirrels out of their boats over the winter. We anticipate that due to the similar physiology of animals in the rodent family, there's a good chance that the No Mouse in the House units will work on other rodents. On the other hand, we expect that our devices would not work well in cases where there is a lot of airflow, such as in the yard or garden. We also aren't sure there is an underground strategy for moles / voles using our units, though this is the number one question we get asked. Our feeling is that moles/voles will simply tunnel around the devices.



The number of units that will be effective depends on the size and layout of the area that you wish to rid of mice. How many spots are there where you think they can get in? If you are setting up a perimeter, you want to place a unit close to each of the possible points of entry where they come in. Additionally it can help to place a unit in each location that they frequent or where you see "evidence". Obviously more is better when you are trying to establish a solid perimeter. If you leave potential entry points undefended, mice will simply prefer those. They can also create new entry points from existing cracks and gaps, so these should either be filled or defended with a No Mouse in the House unit. It may sound like we are just trying to sell more units, but we're simply saying that an effective strategy needs to be complete. If you leave some entry points open, then mice will simply use those. Considering how well they climb and jump, it can be challenging to figure out all the places they can possibly get in. We want all of our customers to get the desired result, keeping mice out, so we always recommend that any possible entry point is blocked with a unit ... and when in doubt, put a unit there.
