I recently killed off an ant infestation. Several weeks later a beetle like insect took over and then some. Never seen them before. They are red with black horizontal bars on their back. They never hold still, constantly crawling. What is this bug and how do I get rid of them?
I can't see this clearly enough to id. However, it appears to be an immature true bug (Hemiptera) possibly a stink bug. I don't think this has anything to do with the ants. If you can get a closer image I'd be glad to take another look. However you could also submit the image to bugguid.net as they have folks there could probably id to species with a clear image.
I can answer questions about the control of pest insects, spiders, mites and related arthropods. These household pests include termites, carpenter ants, powderpost beetles, nuisance ants, bed bugs, cockroaches, fleas, wasps, and many others. I can also answer questions about using pesticides and other pest control tools such as baits and traps.
