Buying Guide: Key Considerations For Wood-Termite Treatments
- Target pest and infestation stage: Choose products that address termites, carpenter ants, and carpenter bees, as well as whether the infestation is visible or hidden.
- Application method: Sprays for surface barriers vs foams for voids and cracks. Consider whether you need a spray can, a concentrate for wood treatment, or a ready-to-use foam.
- Coverage area: Some products treat large areas (gallons or concentrates) while others are best for spot treatments. Estimate your space and select accordingly.
- Durability and duration: Some products offer long-lasting indoor protection (months), while others require more frequent reapplication for ongoing control.
- Wood compatibility: Wood-penetrating products like Bora-Care provide structural protection; surface sprays work well for active infestation and barrier maintenance.
- Safety and ventilation: Follow label directions for indoor use, especially in occupied spaces. Some foams expand and may require ventilation considerations.
- Preventive vs curative use: For new construction, wood treatment concentrates are ideal; for existing structures, surface sprays and foams target current activity.
