Place bait stations in areas of cockroach activity but away from food, children, and pets. 2. Gels: Provided in syringes or tubes for specific applications in cracks, crevices, and other areas such as under appliances and cabinets. Roaches take the bait, and populations are reduced within days. 3. Aerosol Sprays and Residual Treatments
