From the Research
Yes, there are several over-the-counter products designed to seal mattress crevices and prevent bed bug movement, with mattress encasements or covers being the most effective solution, creating a complete barrier that prevents bed bugs from entering or escaping your mattress, as supported by various studies 1, 2, 3, 4, 5. When it comes to choosing the best product, consider the following options:
- Mattress encasements or covers specifically labeled as "bed bug proof" or "bed bug encasements" made from materials like polyurethane-lined fabric with specialized zippers that leave no gaps.
- Diatomaceous earth or silica gel dust can be applied around bed frames and room perimeters for additional protection.
- Bed bug interceptors can be used under bed legs to trap bugs attempting to climb up. It's essential to note that encasements alone won't eliminate an existing infestation, and they work best as part of a comprehensive approach including thorough cleaning, laundering bedding at high temperatures, and possibly professional pest control treatment for severe infestations. The most recent study 5 highlights the importance of considering environmental factors, such as moisture, when applying insecticide dusts, as it can significantly reduce their efficacy. In terms of specific products, Cimexa (92.1% amorphous silica gel) has been shown to be effective against bed bugs, even in the presence of moisture 5. Overall, a combination of mattress encasements, diatomaceous earth or silica gel dust, and bed bug interceptors, along with thorough cleaning and professional treatment when necessary, provides the best approach to preventing and eliminating bed bug infestations.
