As a human with chemical sensitivities, those things are every bit as bad as the spray kind in terms of my eyes and nose burning. I hate restrooms with any variety of artificial scents (which is virtually all, public or in other peoples homes) as it lights my respiratory tract on fire. Canโt imagine how theyโd affect a bird! I wouldnโt use them around birds. And do NOT use that F10 stuff mentioned in another comment! It is scented with PINE oil which is toxic to birds!
We have a small plug in scent warmer in the bathroom

We use about a tbsp of coconut oil as a carrier oil and 10-20 drops of essential oil in it (avoid mints, pine, eucalyptus and tea tree oils). Some good bird friendly oils would be lavender, citrus, sage, jasmine, patchouli, ylang ylang, frankinsense or rose (Iโm sure Iโm missing a few, but thatโs a good list to pick one from). Be sure you buy 100% pure essential oil and NOT fragrance oil. Essential oils will come in small brown or blue glass bottles and likely cost $10-$30. Anything in a plastic bottle or that is really cheap is likely fragrance oil and should never be used around birds. Usually a health food store is the best place to buy essential oils to be sure they are actual essential oils. I would not use complex combinations of oils, just one or 2. I know some people wonโt use even essential oils around their birds, but Iโve never had issues with using oils not known for irritating their respiratory tracts. I, of course, do not use them in close proximity of my bird.
