If there's no sign of spider mites, I would try sprinkling some cinnamon around on the dirt. I read about it right after I threw out a plant that was having the same sort of issue (lol) so I don't have first hand experience, but a lot of people say it works, especially if the plant's been overwatered before and has mold or fungus growing in the soil.
@k_ratoncita I read your other reply where you said there aren't any drainage holes in that pot, so I'd think about repotting it in something else too. Ivy plants don't do well without drainage. Such a cute pot though!
