do mice have problems with caster oil and cedarwood oil? Short answer: yes — mice absolutely have problems with both castor oil and cedarwood oil, but how they react depends on the concentration and how you use them. Here’s the breakdown so you can use them effectively without accidentally attracting mice or wasting time. 🐭 CEDARWOOD OIL — very effective as a mouse repellent Cedarwood oil is one of the few essential oils that has solid evidence for repelling rodents. Why it works Contains cedrol and thujopsene, which irritate rodents’ respiratory systems Overwhelms their scent trails Makes an area feel “unsafe” to them What mice do when exposed Avoid the area Stop nesting in treated spaces Sometimes abandon existing nests if the smell is strong enough What it does not do It does not kill mice It does not work if the scent is too weak It does not work outdoors unless heavily reapplied So cedarwood oil = good repellent, especially indoors or in enclosed spaces. 🐭 CASTOR OIL — mice hate it, but it works differently Castor oil is used in rodent‑repellent granules and mole/vole repellents because rodents dislike: the smell the taste the oily coating on soil or surfaces What mice do when exposed Avoid treated soil Avoid burrowing in treated areas Stop using tunnels or entry points What it does not do It does not harm them It does not repel well in open, windy areas It does not work if applied too lightly Castor oil is more effective for ground‑dwelling rodents (voles, moles, gophers), but mice still dislike it.
