Today I heard that there is a Euphorbia which removes rats from vegetable gardens. Unfortunately I didn't get the specific name of the Euphorbia.
Do you know what kind of Euphorbia it could be (I would say something similar to E. lathyris)? Do you have good experiences?
The only one I know of said to do this is Euphorbia lathyris, or caper spurge (not that the 'capers' it produces are edible, they're toxic if consumed).
Whether you want to put up with an invasive plant in your vegetable patch or not is your choice - it seeds itself prolifically. I'm afraid I've no experience as to its effectiveness as a rodent repellent.
I don't know but in my greenhouse, there is a rat and the only cacti he ate, out of many palatable options, was my euphorbia medusoid.
