| Welcome to the forum Callie! Ants in and of themselves do not harm orchids, but they unfortunately have a nasty habit of bringing other nasties with them including aphids and mealy bugs - which they then "farm" the nectar from both insects and exuding sweet liquid from the orchids. Never heard of using hydrogen peroxide for pests - it is usually used as a "natural" treatent for disease organisms. Thre are a number of products made to stop ants outside the home by putting a perimeter around and then a number of products that will rid you of the inside ants as well - my favorite is terro liquid ant baits. |
