Trying to identify what kind of cockroach to inform exterminator strategy. Here are relevant facts for context:
- location San Francisco area California
- found two nymphs like this two nights in a row on bathroom floor of the single family detached home I moved into two months ago
- house has a very overgrown yard with a lot of rotting wood, mulch and vegetation, it rained excessively during February and March
- I found a very dark almost black cockroach on the ground outside when I initially moved in but don’t have an image as the area was disturbed by construction work since then
- Have been getting lots of packages in cardboard boxes piling up
Which kind of roach nymph?

Re: Which kind of roach nymph?
Uncertain, but it may be a nymph of the American cockroach (Periplaneta americana) -

Over the years, I've used bait stations (large roach) to control this species, with considerable success. In my case, they seem to be more of a seasonal, intermittent problem, than a continuous one.
