Black and white hemiptera shield bug, doesn't stink

ThreeEyes Los Angeles, CA Jun 29, 2015

Can anyone help identify these? We have an infestation on our house wall outside. There is no bad smell, though they look like black and white versions of a stink bug.

We're in Los Angeles.

The babies are not red or orange, they're black and white. Could this be a harlequin bug?

What's the best way to remove them, preferably chemical free?

Definitely Bagrada bugs; Harlequin bugs are much larger -

Here is a page that has some options, but it doesn't seem there are a lot of biological controls.

Thanks. We had pest control out, and he said they are young Box Elder Bugs. They certainly look like Bagradas to me.

I am not sure I would hire that company again... look at this

The last three images of yours are pairs mating and young insects would not do this that I am aware of. I could be wrong, but it seems that Flapdoodle has it correct. If you read the page it mentions the females are larger than the males, so maybe the babies you are seeing are really adult males. ??

Even with the possibly wrong Id, did the company solve the problem?
