As the title states, I need help deciding if this is a German cockroach, or a field one(and if it is a German cockroach if I should be worried or not/what steps can I take to prevent a infestation.). I had just got done going number 2 and sat in my chair to play my pc, and this little guy runs across my desk jump scaring me. Then I tried to grab it with toilet paper to crush it missed and finally grabbed it. Idk how it got into my room since the only way it could’ve gotten in is through my window which is closed, but is next to a bunch of outside flowers. There’s only one and I don’t see any egg casings. Any help would be much appreciated! (Sorry for the bad photos)
