Tiny biting insects
I live in South Texas, where it gets very hot and humid. For the past several years we have been plagued by a tiny biting insect that is almost microscopic. They swarm and they are yellow and look almost exactly like pollen. They land on you in swarms and sting so bad you have to run inside. They've never been as bad as this year and I've seen them by the thousands on my Hibiscus plant,(esp. the flowers). What are they? Are they hurting my plants? How can I get rid of them?

Biting midges(sometimes called "no-see-ums")are a nuisance to people but don't hurt plants. They thrive in wet conditions - is your hibiscus overwatered? Are there wet leaves or bark rotting underneath? The best way to control these flying pests is to clean up any poor drainage or damp rotting matter around your yard. Repellents with DEET that you apply to your skin are listed for biting midges. Most window screens can't keep them out - getting screening that has very small openings can be hot, too. The movement of overhead fans does keep them away.
