Advertisement Question regarding B. Lateralis, If a nymph or two escapes. What are the chances of it becoming an annoying pest and invading my home? I've had only one actual escape, which was a nymph about 3/4''. It has been 7 months, since before winter came, but no signs of it. Even with traps hoping to catch it in my basement (where I keep my T.'s and feeders) there's nothing. So what are the chances if another nymph escapes and reproduces with the previous escaped B. lateralis?? Winter is almost over here and spring temps are returning. So it's just a question in curiosity.
