I honestly wouldn’t care if it stayed at one or two of them, but I know if I leave these things and treat them as pets I will get an infestation in no time.
And with each new one the chances of me feeling one of them walk on my arm increases, and I am not letting that happen.
Meh, don’t need them to end an infestation. Just killing the few roaches that might exist somewhere around is enough to pay their rent.
If I find one close to my face on the other hand, the place it considered territory would be wiped off the map. It would become an endangered species.
