I have this tropical Hibiscus that I brought in from outside. I also brought in another plant and found that the other plant had this little clear bugs crawling around and had all this little white stuff on the leaves. I sprayed it with water with dish soap but could not get rid of them so I put it outside and let it freeze. Now I noticed the same thing on my tropical Hibiscus. Does anyone know what it is and how I can get rid of these little bugs before it destroys my plant?

Bugs look to fuzzy to I.D. send close up, using magnifying glass.

Likely, aphids. Use 1 Tbl regular dawn dishsoap, to a gallon of water. Spray both sides of leaves and stems. Let dry for a while. They should wash off then.

Thanks Philip. I will try to get a better picture. I tried dawn in water but it didn't seem to work.

I read part about soapy water, but did you let it dry for a while. The soapy water basically, coats, and glues bugs down, then they die.
If you did that !
Then go to next level, Insecticidal Soap spray !
You can buy it, or find a diy recipe on net.

Jeanne - It's not clear from the photos just what those critters are. Regardless, the key to getting rid of them is thoroughness of coverage when you spray.

I suggest that you start by pruning back your Hibiscus as much as you can stand. Hibiscus benefit from substantial pruning in the late winter anyway. Then, mix a solution that is 5 parts water, 1 part alcohol and a squirt of liquid dish soap (works just as well as insecticidal soap). Be sure to spray all remaining leaves and stems until they are dripping wet and then wipe all of them down with paper towels.

@WillC Thanks, Will. I will give that a try tomorrow. I really hate to loose this plant. If I take the branches that I prune outside and let them freeze, will that take care of any pests that are on them? Or should I also treat them? This is the first time I have ever had to deal with this problem. I really don't want it to affect my outside plants this spring/summer.

Don't worry, outside the forces of nature will take care of the pests appropriately. But you may want to just put the affected stems and leaves in the garbage. For sure, keep them out of the house.
