For the past 4 years, we've brought our braided hibiscus tree in the house (We live in Michigan) for the winter and it has done well with no problems. This year, however, the plant is doing just as well, but we're noticing little tiny 'no see em' type bugs in the house drawn to the lights. There are no other plants in the house, so we know it's the braided hibiscus.
We have occasionally found a flower bud with black dots (bugs) and cut them off, but since being indoors this year, that has happened only once. For that problem we spray a misted mild dish soap solution on the tree and it's fine. What can we do for these pesky tiny flying bugs?
