can send a pic of that trap? because its said here that the cockroach trap with poison will kill them but they can die on hidden places in the car, hence yucky with the dead bodies in your car and could smell.

so far i see no "live" cockroach in the car, but a small dead one which died probably due to intense interior heat when under the sun. however my car has windshield cover now, and moreso a car cover, hence protected from sun and rain, but now i realize the environment within is friendlier to cockroach or whatever.

i just want to be proactive.
