Yes, I noticed...which is why I told him to remove Jade and her tank from the apartment when the exterminator comes and to keep her out for a day after. As Ashley said, if there is a roach infestation, this can be very dangerous to the people and animals in the house and must be dealt with. I have an exterminator that comes once a month...and again, as Ashley said, my exterminator is familiar with pesticides that are harmful to reptiles and animals and I always discuss options and types of chemicals used before he uses anything in my home.
