What are these worms eating my Hibiscus? They are really small.

Hibiscus sawfly perhaps, a.k.a. Atomacerca decepta. To see a picture, go to this link and scroll down, looking for "Sawfly larvae", "hibiscus sawfly" or "Atomacera decepta": http://images.search.yahoo.com/search/images/view?back=http%3A%2F%2Fimages. search.yahoo.com%2Fsearch%2Fimages%3F_adv_prop%3Dimage%26fr%3Dyfp-t-471%26v a%3Dhibiscus%2Bsawfly%26sz%3Dall&w=461&h=301&imgurl=www.robsplants.com%2Fim ages%2Fcritters%2FAtomaceraDecepta050622.jpg&rurl=http%3A%2F%2Fwww.robsplan ts.com%2Fcritters%2Fcrawlers.php&size=61.1kB&name=AtomaceraDecepta050622.jp g&p=hibiscus+sawfly&type=jpeg&no=4&tt=25&oid=8cbc252b41570756&ei=ISO-8859-1

You can see another picture in this simpler PDF link; just do a find on "Atomacerca": http://www.agnr.umd.edu/ipmnet/05Jul15L.pdf Orthene can be used to control the larvae. Try Bt (Bacillus thuringiensis) if you prefer organic minded solutions.
