Bora-Care Termiticide Insecticide and Fungicide Concentrate

Bora-Care penetrates deep into wood fibers to eliminate and prevent termites, carpenter ants, wood-boring beetles, and decay fungi; protects your structure for the life of the wood. It applies directly to wood surfaces with a 2-foot band treatment and covers about 800 square feet per gallon. Ideal for both new builds and existing homes, it offers whole-house protection when applied during the dried-in phase.
Best for: New construction or remodels where a long-lasting wood treatment is desired. Limitations: Requires proper surface preparation and follow-up application to maximize protection.
Nisus Tim-BOR Professional Insecticidal Dust

Tim-BOR Professional is a versatile borate powder usable as a dust, liquid, or foam for wood surfaces and concealed spaces. It protects against wood decay and insects, including termites and carpenter ants, with effects lasting over time. It is designed to be non-staining on wood and non-corrosive to construction components.
Best for: Targeted treatment in hidden cavities or along framing where conventional liquids can be hard to reach. Caution: Dusting must be done with appropriate containment to avoid inhalation exposure.
Rockwell Labs BAIP001 BorActin Insect Dust

BorActin is a boric acid-based dust approved for broad-use pest control, including termites, cockroaches, and other insects in residential, commercial, and agricultural settings. It remains active until removed and is moisture-resistant, helping to maintain protection in various environments. It is suitable for use in non-food and food areas depending on labeling.
Best for: Broad indoor or outdoor dust applications where moisture resistance is beneficial. Limitation: Should be applied with care to minimize exposure in living spaces.
System Three Resins Borate Powder

Board defense borate powder is an EPA-registered insecticide, termiticide, and fungicide concentrate for control of wood-destroying insects and rot. It is a versatile product for protecting and treating wood against various wood-destroying organisms. The powder is water-soluble and suitable for multiple wood protection scenarios.
Best for: Comprehensive wood protection in projects with varying moisture exposure. Limitation: Application requires proper dispersion to ensure even coverage.
Spectracide Terminate Termite Killing Foam

Termite killing foam expands into voids and channels, allowing contact with exposed termites and related insects. It is designed for indoor and outdoor use and provides ongoing control up to several months indoors. It also targets carpenter bees and similar pests in treated areas.
Best for: Quick, surface-to-void treatments where termites are visible or suspected in void spaces. Limitation: Not a long-term wood protection solution alone; may require supplemental treatments for lasting protection.
Buying Guide: Key Considerations For Borate Wood Treatments
- What form suits your project? Concentrates require mixing and application, while dusts and foams offer easier targeting of hidden spaces.
- Where will you apply it? Exterior wood, framing, and dry-in phases may benefit from deeper penetration borate treatments.
- Is the product labeled for your structure type? Choose products appropriate for residential, commercial, or agricultural settings as labeled.
- Do you need moisture resistance? Some borate formulations stay active in damp environments, while others may require reapplication after moisture events.
- What is the scope of protection? For whole-house protection, a concentrate applied during construction can be more effective than spot treatments.
Frequently Asked Questions
- What is a borate spray used for termites? A borate spray or powder is a boron-based treatment that penetrates wood to kill termites and prevent new infestations by inhibiting insect growth and fungal decay.
- Are borate treatments safe for indoor use? Yes, when applied according to labeling, borate products are designed to be low-odor and relatively low-toxicity for enclosed spaces, but proper PPE and ventilation are recommended.
- How long does borate protection last? Protection can be long-lasting if the wood remains dry and properly treated; moisture and new wood exposure may require reapplication in some cases.
- Can borate powders be used in hidden or hard-to-reach areas? Yes, powders and dusts are often the best option for reaching concealed framing and voids where termites hide.
- Should I choose a spray or dust borate product? Sprays are ideal for wood surfaces and larger areas, while dusts target cracks, joints, and cavities more effectively.
- Can borate treatments be used with other termite controls? They can be part of an integrated approach, but always follow product labeling and local pest-control guidelines.
