This Straight Talk! episode isn’t for the squeamish. But it’s very interesting. One pest that we never, ever want to see anywhere but that can quickly overtake a home or building is the dreaded cockroach. Maybe you have come into a dark room, turned on a light, and there it is, staring at you. And you know there’s a large family of them somewhere nearby, perhaps in the wall just waiting to come out and add to the drama that you want no part of. Jennifer Gordon is an urban and medical entomologist with Bug Lessons Consulting and she provides valuable perspective about cockroach activity, why they come inside, what they eat, and especially how they impact sanitation and health.
