Yes, you can spray peppermint oil mixed with water as a natural repellent for pests like insects and rodents, or as a room/surface freshener, but you must dilute it and test surfaces first; it's effective for repelling pests due to its strong scent, but it's not a killer, so reapplication (weekly or more often) is key, and it's best used for soft-bodied garden pests, not large ones, and avoid spraying flowers to protect pollinators.
To make a peppermint oil spray, you need pure peppermint oil, water, and dish detergent. Mix two teaspoons of peppermint essential oil with 1 cup of water and add 3 to 5 drops of detergent. Shake the bottle to mix the solution. Spray the solution in problem areas where you have seen mice activity.
Instructions
Mix 10–15 drops of peppermint oil with one cup of water and a teaspoon of mild dish soap. Spray the mixture directly onto ant trails, nests, or entry points. Reapply every few days, as rain and sunlight break down the scent quickly outdoors.
A common mix is 10 to 15 drops of peppermint essential oil in 1 cup of water with 1 teaspoon of mild dish soap to help the oil disperse. Peppermint oil evaporates quickly. Expect the scent to fade within hours and reapply every few days for consistent deterrence.
Peppermint oil repels a wide variety of common pests, including mosquitoes, ants, spiders, roaches, flies, fleas, moths, and beetles, along with some garden pests like aphids and whiteflies, and even small rodents like mice, due to its strong menthol scent that disrupts their senses. It works best as a deterrent in a spray or diffuser around entry points, but its effectiveness is temporary, requiring frequent reapplication, especially outdoors, says The Spruce and Pestco Professional Services.

Cautions with other medicines
The 30/50/20 rule for essential oils is a blending guideline for creating balanced, harmonious scents, suggesting you use 30% top notes, 50% middle notes, and 20% base notes for longevity and depth. Top notes are light and fast-evaporating (like citrus), middle notes are the heart of the blend (like florals/herbs), and base notes are grounding and long-lasting (like woods/resins). For a 10-drop blend, this means 3 drops top, 5 drops middle, and 2 drops base.
Directions. Combine water and peppermint oil in a spray bottle. Shake bottle before use and spray the solution around entry spots such as windowsills and door frames, or places where insects may hide. The strong odor acts as a repellent.
Large doses of menthol, a key ingredient in peppermint oil, can be poisonous. This can lead to serious side effects, including seizures, slow heartbeat, and irregular breathing.
This active ingredient is an insecticide derived from the peppermint plant. Peppermint oil may repel insects, mites, or vertebrate pests. Insects and mites can be killed when oils block their breathing structures.
When spraying liquid to kill and control bugs, spray with the wind to avoid getting drenched. Spray where dissimilar building materials meet –where siding joins window frames or where brick meets wood trim. Spray areas where utilities enter the structure and around doors and windows.
Bugs hate strong, pungent, or overpowering natural scents, with peppermint, citronella, lavender, eucalyptus, and tea tree oil being top contenders, alongside vinegar and certain herbs like basil and rosemary, which disrupt their navigation and sensory systems. While no single scent universally repels all bugs, these strong aromas create an unpleasant environment, making them effective natural deterrents for common pests like mosquitoes, ants, and flies.
Vinegar is reported as being able to repel ants, mosquitoes, and spiders. In many situations, the impact of vinegar on these pests is short-lived and ineffective, so it is best to contact your Orkin Pro for effective, customized pest control treatments.
If you have spiders, ants, mosquitoes and other bugs around your home, try using peppermint oil. The scent may also help keep mice away. As per Orkin, peppermint oil for bugs may also help ward off aphids, beetles, fleas, caterpillars, flies, moths and lice.
Spray Application: Mix 15-20 drops of peppermint oil with one cup of water and a few drops of dish soap (to emulsify the oil). Spray this mixture directly on mattresses, bed frames, carpets, and furniture seams where bed bugs may be hiding.

Peppermint oil is another powerhouse in the natural deterrent arsenal. Its strong, minty scent is one of the smells insects don't like, especially ants, spiders, and even mosquitoes.
