What are these little critters!
Brought in the hibiscus tree a few weeks ago, and we noticed these little bugs on it earlier this week and we have no idea what they are. Most are black, but a few are red. They are on the bark of the tree, not on the leafs. There are a few small webs on the tree. Any help is much appreciated!
Although we couldn't see them clearly in the photos, they appear to be one of the large species of thrips. Hibiscus is known to host a large thrip species. Here are photos and info: https://extension.umd.edu/hgic/topics/thrips-houseplants
You can use a houseplant insecticide for these. Horticultural oil, horticultural soap and the ingredients pyrethrin or spinosad all should be effective on thrips. You might want to take the plant outside on a mild day in order to spray. Cover all plant surfaces.
Follow the insecticide label directions, especially be aware of temperature limits.
A plant this infested is a danger to your other plants. You might consider returning it immediately or disposing of it.
