I’m a very nervous plant parent, so I check my guys for pests all the time. Today I stumbled upon some tiny black bugs on my arrowhead plant, as well as what appeared to be larvae inside one of the new leaves? Please suggest what to do! There does not appear to be any damage from them (sun damage to the plant previously) and I’ve taken off all I can see. If more show up I’ll add photos, but for the meantime, are there any suggestions?
