What deters cats who spray?

[Thesebootsweremadeforwalking]

Our garage door reeks of cat pee to the extent that the smell is permeating the house. We have a spayed female who chose to move outdoors when we moved house last year, and she has a catflap into the garage where she has a cat igloo and is where we feed her (she comes in when she's cold, but otherwise basically lives in the garden and garage).

We're guessing the spraying is one of the toms who regarded the garden as their own, before our cat arrived.

We've washed the door and disinfected, is there anything else we could do? Any tips very much welcomed!

Orange zest sprayed on the area should work I have read that stops them

Trapping and neutering them works best ...

TBH I was thinking more of how to clean up properly then dissuade them from coming back!

I'm really wondering if this might be my cat's last year. She seems stressed out (she's 15 btw), she's soiling in the garage (is usually very clean) and she's not eating as much as usual. I hadn't really considered that the toms/ territory thing might be linked until I posted here. Hmm.

Thanks for the tip re: orange zest, I'll try it. Would zest in water make a reasonable spray or is it something you'd have to buy?
