Q.Hibiscus pest?
My hibiscus tree, which is indoors now, has developed ‘something’. The leaves, though they appear healthy, have scattered small holes in them. They are perfectly round as if made with a small drill bit. I don’t see any visible ‘bugs’ but it’s gotta be something. Until I can find out, I don’t know how to treat it. Thanks for your help. Kat
Tiny holes are usually attributed to flea beetles, and although those are mainly found on vegetables, there are so many different types that there could be one that has taken a liking to your hibiscus. Sawflies is another possibility. All of these are usually found outdoors, of course, but it's possible that some hatched from the soil in the plant you brought indoors. https://www.gardeningknowhow.com/plant-problems/pests/insects/what-are-flea-beetles.htm
Unless it appears that the amount of damage is increasing, I wouldn't worry about it. If damage appears to be increasing, you can take leaf samples to the county extension service for analysis. This link will help you locate the nearest office: https://www.gardeningknowhow.com/extension-search/
You can spray with insecticidal soap or neem oil, even if you can't identify the bug. This article has more information: https://www.gardeningknowhow.com/special/organic/natural-home-pesticides-organic-garden-pest-control.htm
