Excellent Materials: Made of high-quality materials, this trap is durable, impact-resistant, and odor-free, ensuring reliable performance during use. Safe and Environmentally Friendly: This trap operates without radio waves or electricity and contains no toxic substances. It is safe for use around children, pets, and sensitive individuals. Easy to Use: Simply place bait inside, close the lid, and position the trap in areas prone to cockroach activity such as bathrooms, storage rooms, garages, or behind appliances.
