Bora-Care Termiticide Insecticide and Fungicide Concentrate
Bora-Care is a widely used wood treatment that penetrates deep into wood fibers to eliminate and prevent termites, carpenter ants, wood-boring beetles, and decay fungi. Its protect-once approach can shield a structure for the life of the wood when applied correctly. The concentrate is designed for direct wood application, making it suitable for new constructions and existing homes during the dried-in phase to provide comprehensive protection against dry wood and subterranean termites.
Key points include a 2-foot band treatment for efficient coverage and an approximate 800 square feet coverage per gallon. This product is particularly valued for its ability to create a durable baseline defense within the wood, reducing the risk of future infestations and damage. While it requires proper handling and mixing, its long-term protection often makes it a preferred choice for professionals and informed homeowners alike.

Buying Guide: Key Purchase Considerations
- Target pests and wood type: Choose products based on the specific pests (termites, carpenter ants, wood-boring beetles) and whether you are treating bare wood, finished surfaces, or hidden cavities.
- Application method and site: Consider whether you need a spray, brush, dust, or foam delivery, and whether the treatment will be applied during new construction or to existing structures.
- Coverage and labor: Look at coverage per gallon or per bag, and plan for potential labor savings with ready-to-use formulas or concentrate that requires mixing.
- Aesthetic impact: If wood discoloration is a concern, prioritize formulations designed to be non-staining or that preserve the wood’s natural appearance once dry.
- Safety and compatibility: Ensure compatibility with existing finishes and hardware. Verify that products are non-corrosive to screws, nails, and other fixtures to preserve structural integrity.
- Regulatory and environmental considerations: Check EPA registration status and local guidelines for wood protection treatments, especially for indoor use and in sensitive environments.
- Long-term protection vs. upfront cost: Borate treatments typically offer long-term protection, but initial costs and labor should be weighed against expected durability and maintenance needs.
- Professional versus DIY use: Some products are optimized for professional application due to mixing or handling requirements; others are ready-to-use for homeowners.
