WC Blatta orientalis ?

[bwhatch2]

i live in nebraska and found these guys today under a big water filled tub. can anybody help me identify them? i am thinking (hopeing) they are Blatta orientalis ,. any ideas? i can try to get better pics if needed. a couple things that might help id them. i found ooths with them that pretty much identical to my b.lat's ooths and they are not very good climbers. they can kind of a little bit climb up the side of a deli cup but are really bad at it.

Most of those are Blattid nymphs, probably B.orientalis. However the nymph in the first pic on the far left is a Parcoblatta. You can tell because the last abdominal segment ends in a single point rather than being cleft.

oh snap, gonna get rid of them. not brave enough to culture a pest species. that said, I though b.orientalis were expert climbers, these are not good climbers at all

Adult male B.orientalis can climb smooth surfaces but that's it.

ahhhh, I got myself all messed up here.
I originally thought the were Blatta orientalis ("water bugs") which is what I was hoping they were. which is what you confirmed them to be. not sure how I got in my head these were invasive.

so just to clarify, these are Blatta orientalis aka water bugs, and non invasive. correct ? (and THANK YOU for identifying these for me !)

Well Blatta orientalis are invasive, but if you mean house pests no, they tend to only infest sewers and other very moist areas around human habitation, rather than houses themselves.

Big exception is if you have a consistently wet area, like around a leaky hot water heater or something. I used to work in a dog food & livestock feed warehouse, and there was a badly leaky water heater where ungodly amounts of them had setup shop. Between unlimited high protein feed, consistent moisture & the heat from the water heater it was wild. That entire wall next to the heater was completely full of them.
