I found this bug on my shower curtain this morning. They are all over my yard outside. I think they may eat my garden? I live in AZ and my home is surrounded by oleanders. I find them a lot around plants or on my outside walls. They have 6 legs, antenaes, and are grey, black, and red with a white spot on them. What are they and how do I get rid of them?
Your photo is of the small milkweed bug. The adults and nymphs feed on seeds of a wide variety of plants. They are also known to suck nectar from flowers and have been reported to be predators on other insects.
It is not considered a garden pest. If you feel they are causing a problem you could collect them by hand and put them in a container of soapy warm water.
