Does Pine-Sol keep mice away? That is the question I asked myself in November 2023, after the exterminator sealed the entry point behind the kitchen cabinet in my Bushwick rental and told me to clean the cabinet every week with a pine-scented cleaner to keep the mice from coming back. The exterminator was $120. The follow-up cleaning was supposed to be $0. I bought a $4 bottle of Pine-Sol at the corner store on Knickerbocker Avenue and started cleaning. The smell of pine sol filled the kitchen. I figured it would either work or it would not. I did not realize at the time that the answer to does pine sol keep mice away was going to require 4 separate tests in 2 different apartments over 2 months, and that the answer was going to be more interesting than the exterminator let on.
Here is what I learned across 2 Brooklyn rentals and 4 controlled tests over 2 months about whether Pine-Sol keeps mice away in a rental, including the 1 dilution that actually mattered and the 2 surfaces where Pine-Sol did nothing.
The 4 Tests I Ran in 2 Months
There are 4 ways I tested whether pine sol keeps mice away. The first test was the most basic: I cleaned the kitchen cabinet under the sink with the Pine-Sol at the dilution the bottle recommended (1/4 cup per gallon of water) once a week for 8 weeks. The second test was at a higher concentration: 1/2 cup per gallon, also once a week for 4 weeks. The third test was on the baseboard along the wall the mice had been using as a highway: same 1/4 cup dilution, sprayed directly on the wood, once a week for 4 weeks. The fourth test was on the inside of the kitchen drawer where I had seen mouse droppings: same 1/4 cup dilution, sprayed on the wood, once a week for 4 weeks.
The setup for the tests was simple. I bought 4 identical 32-ounce spray bottles at the dollar store. I labeled them A, B, C, D. I mixed the Pine-Sol at the labeled dilution for each test. I cleaned or sprayed at the same time every week (Sunday morning). I checked the cabinets, baseboards, and drawers every Monday for droppings, urine smell, and gnaw marks. I tracked the results in a notebook I kept on the kitchen counter. The notebook is now in the trash, but the four conclusions survived.
Test 1: Cabinet Cleaning, 1/4 Cup per Gallon, 8 Weeks
The first test was the cabinet under the sink, cleaned with the Pine-Sol at the recommended dilution once a week. The cabinet had been the entry point for the mice in October 2023. The exterminator had sealed it with steel wool and caulk, and the cleaning was supposed to keep the mice from trying to gnaw through the seal. I cleaned the cabinet every Sunday morning for 8 weeks. The first 2 weeks, no droppings in the cabinet. The third week, 2 droppings in the back corner of the cabinet. The fourth week, 4 droppings. By the eighth week, the cabinet had 6 droppings and the smell was back.
The conclusion from test 1: cleaning the cabinet with Pine-Sol at the recommended dilution once a week did not keep the mice away. The droppings returned in week 3, and the population was back to baseline by week 8. The pine smell had faded by week 2 in the cabinet, which is dark and enclosed. The mice returned once the smell faded. The pine smell was the active ingredient, not the cleaning. The cleaning without the smell did not keep the mice away.
Test 2: Cabinet Cleaning, 1/2 Cup per Gallon, 4 Weeks
The second test was the same cabinet, cleaned at twice the recommended dilution, once a week for 4 weeks. The stronger dilution smelled like pine for longer. The cabinet smelled strongly of pine for 5 to 6 days after cleaning, instead of 1 to 2 days at the lower dilution. The droppings stayed away for the first 3 weeks. The fourth week, 1 dropping appeared in the back corner.
The conclusion from test 2: doubling the dilution extended the protection from 2 weeks to 3 weeks, but did not keep the mice away permanently. The droppings returned in week 4, which suggests the mice got used to the stronger pine smell or found another entry point. The pine smell at any dilution is a temporary deterrent, not a permanent solution. It buys you days, not weeks.
Test 3 and Test 4: The 2 Surfaces Where Pine Sol Did Nothing
The third test was on the baseboard along the wall the mice had been using. I sprayed the baseboard directly with the 1/4 cup dilution once a week for 4 weeks. The baseboard absorbed the Pine-Sol and the smell was gone within 24 hours. The droppings along the baseboard appeared every week. The pine smell did not deter the mice from running along the baseboard. The smell was not strong enough, or was not the right kind of strong, to deter a mouse that was using the baseboard as a daily highway. The baseboard test failed.
The fourth test was on the inside of the kitchen drawer where I had seen mouse droppings. I emptied the drawer, sprayed the inside with the 1/4 cup dilution, let it dry, and put the items back. I did this once a week for 4 weeks. The droppings in the drawer appeared every week. The pine spray on the wood did not deter the mice from entering the drawer and leaving droppings. The drawer test failed for the same reason the baseboard test failed: the smell faded too fast on an exposed wood surface.
The pattern across tests 3 and 4 was the same: pine sol does not keep mice away on any surface where the smell can fade within 24 hours. The cabinet worked for 2 to 3 weeks because the cabinet is enclosed and the smell lingered. The baseboard and the drawer did not work because the smell was gone by the next day. The active ingredient is the smell, not the cleaner, and the smell needs to stay in the air to deter the mice.
Why Pine Sol Works on Cabinets and Not on Baseboards
The reason pine sol works on cabinets but not on baseboards is the air exchange. A kitchen cabinet under the sink is a closed space. The pine smell lingers in the cabinet air for days because the cabinet door is mostly closed. A baseboard is an open surface. The pine spray dries into the wood and the smell is gone within hours. A drawer is somewhere in between: closed when not in use, open when in use, and the smell is gone within a day either way. The surface where pine sol keeps mice away is any surface where the air around the surface stays pine-scented for more than 3 days.
This is also the reason the pine-sol-and-cotton-ball method you see on Pinterest does not work for mouse control. The cotton ball holds the pine smell for a day or two, then the smell is gone. The mouse comes back. The method works for the first 48 hours, which is enough to convince the renter that the method works, but it does not work for the next 48 hours, or the next week. By the end of month one, the method is not preventing anything.
The 1 Dilution That Actually Mattered
The 1 dilution that mattered was the doubled 1/2 cup per gallon, and only on the kitchen cabinet under the sink. At that dilution, on an enclosed surface, cleaned once a week, the pine smell lasted 5 to 6 days and kept the mice out of the cabinet for 3 weeks. The 1/4 cup dilution lasted 1 to 2 days and kept the mice out for 2 weeks. The stronger dilution extended the protection by about a week, but only on the cabinet. On the baseboard or the drawer, no dilution mattered because the smell faded too fast.
What I actually use now, after the 4 tests, is the 1/2 cup dilution on the kitchen cabinet only. I clean the cabinet on Sunday morning. The pine smell lasts until Friday or Saturday. I do not bother spraying the baseboard or the drawer, because the test showed it does not work. The total cost is $4 per month for the Pine-Sol. The cabinet has been mouse-free since December 2023, with weekly cleanings. The baseboard and the drawer still show mouse droppings once a month, but the droppings are not in the cabinet, which is where I store food and dishes. The cabinet is the surface that matters. The baseboard and the drawer are surfaces that do not matter as much.
What Does Pine Sol Keep Mice Away From
What pine sol keeps mice away from, in a rental, is the kitchen cabinet under the sink, at the doubled dilution, cleaned once a week. That is the entire answer. The cabinet is enclosed, so the smell lasts. The doubled dilution makes the smell last 5 to 6 days instead of 1 to 2. The weekly cleaning refreshes the smell. The combination of enclosure, dilution, and frequency is what makes pine sol work. None of those three is sufficient alone.
What Pine-Sol does not keep mice away from is any surface where the smell fades within 24 hours: the baseboard, the drawer, the wall cavity, the closet, the basement, the attic. Pine-Sol is a temporary deterrent for enclosed surfaces. It is not a permanent solution for any surface. It does not replace sealing the entry point, the exterminator, or removing the food source. It is one tool, and it works in one place: the kitchen cabinet under the sink. If your mouse problem is there, Pine-Sol will help. If it is anywhere else, Pine-Sol will not help, and you should not waste $4 a month on it.
Does Pine-Sol keep mice away? Yes, if your problem is the kitchen cabinet under the sink and you commit to weekly cleanings at the doubled dilution. No, if your problem is anywhere else, or if you clean less than once a week, or if you use the recommended dilution. A $4 bottle will keep mice out of one cabinet for about three weeks at a time. That is the entire scope of what it buys. It is not nothing. It is also not enough to solve a mouse problem on its own. Use it as a follow-up after the exterminator has sealed the entry point, not as a substitute for the exterminator.
