PenaShield Penetrating Wood Preservative

PenaShield is a ready-to-use borate-based preservative designed to penetrate wood deeply, delivering long-lasting protection against termites, carpenter ants, wood-boring beetles, and decay fungi. The formula is suitable for decks, attics, and wood-working projects where untreated surfaces are prone to infestation. Once dry, treated wood can be painted, sealed, or stained without discoloration, preserving a natural wood appearance. This makes PenaShield ideal for homeowners looking for a straightforward application with durable indoor protection and compatibility with common finishes.
Key benefits include deep penetration that creates a protective barrier inside wood fibers and a formulation that minimizes staining or color change after drying. It’s especially useful for protected indoor spaces or construction gaps where pests may access wood from hidden voids. Application involves spraying or brushing directly onto untreated wood, making it a practical choice for DIY projects and larger woodwork tasks alike.
Nisus Tim-BOR Professional Insecticidal Dust

Tim-BOR Professional is a versatile borate-based wood preservative available as a dust, liquid, or foam. Its flexibility allows treatment of exposed wood surfaces and hidden spaces, delivering long-lasting control against drywood termites, carpenter ants, and wood decay fungi. It is designed to avoid discoloration and is non-corrosive to screws and nails, helping maintain the structural and aesthetic integrity of wood frames, trim, and cabinetry. The product serves well for both preventive and remedial applications in diverse environments, including attics and basements.
Applications span from surface dusting to deeper injections in voids, making Tim-BOR a strong option for professionals and serious DIYers seeking a preventive safeguard or remedial treatment against wood-destroying insects and decay. The non-staining nature supports preservation of finished wood while maintaining interior and exterior appeal.
Advance Termite Bait Station Wood Bases (25 Count)

This product line provides replacement wood inserts designed for BASF’s Trelona/Advance termite monitoring bases. It constitutes an essential component of a monitoring and control system, enabling proactive termite management with compatible bait bases. Note that these wood inserts are not insecticide themselves but are used within a larger baiting system to monitor termite activity and support effective control programs. They’re suitable for retrofit in existing monitoring stations and new installations where wooden inserts fit the station design.
For users prioritizing ongoing termite surveillance and a structured treatment approach, these wood bases help maintain a robust monitoring framework, ensuring timely interventions when activity is detected. They work best as part of a comprehensive, brand-consistent termite management plan that includes proper bait placement and routine inspection.
Advance Termite Bait Station Monitoring Wood Insert

The wood insert for BASF’s monitoring stations is designed specifically for termite detection and control systems. It provides a physical substrate within the monitoring station to attract termites and facilitate inspection. This insert is not an insecticide by itself, but it plays a critical role in a monitored approach to termite management, enabling property owners and pest control professionals to track activity and deploy targeted treatments when needed.
Effective monitoring relies on consistent inspection and a responsive treatment plan. The wood insert supports a proactive strategy, helping to minimize wood damage by enabling earlier detection and intervention, especially in attics, crawlspaces, and wall voids where termites often begin their activity.
Termidor Foam 20 oz

Termidor Foam is a non-repellent termiticide/insecticide designed to be applied as a ready-to-use foam that expands deeply into voids, nests, and galleries. The expansion ratio of about 30:1 allows deep penetration into hard-to-reach areas, delivering targeted treatment without the need for disruptive whole-house fumigation. Its thicker foam structure creates durable cell walls that can remain active longer than competing products, making it suitable for treating wall voids, decks, fencing, utility poles, and tree hollows. This makes Termidor Foam a strong choice for spot-treatment strategies aimed at interrupting termite colonies at the source.
Guidance for use emphasizes precision application to avoid oversaturation and ensure you reach critical infested zones. It is especially effective for homeowners and professionals who prefer a compact, effective solution for visible termite activity and suspected nesting sites, providing a practical balance between coverage and control.
Buying Guide: Key Considerations For Wood Protection And Termite Control
When selecting products to protect wood from termites and related pests, consider the wood environment, infestation risk, and maintenance plan. The following perspectives help shape a well-rounded approach:
- Penetration vs. surface protection: Deep-penetrating preservatives (like PenaShield) protect within wood fibers, while surface coatings can offer barrier protection but may require reapplication after wear or moisture exposure.
- Preventive vs. remedial focus: For new wood, preventive treatments help reduce future risk; for existing structures with activity, targeted measurements (dusts, foams, or monitoring inserts) support remediation without wholesale replacement.
- Indoor vs. outdoor suitability: Exterior wood endures moisture and temperature changes; interior wood often benefits from low-odor, low-stain formulas to preserve finish and appearance.
- Application method and accessibility: Ready-to-use liquids, dusts, or foams offer varying ease of use. Consider hidden void access and whether professional equipment is required for safe, effective treatment.
- Monitoring and maintenance: Bait stations and monitoring inserts enable ongoing surveillance. Pair monitoring with periodic inspections to detect early signs of activity and adapt treatments as needed.
- Compatibility with finishes: If wood is already finished, choose products that dry clear or remain compatible with paints, stains, or sealers to maintain aesthetics.
- Safety and environmental impact: Select products with documented safety profiles for indoor air quality and minimal environmental impact, especially in homes with children or pets.
Comparison Snapshot
- Penetration depth: PenaShield offers deep penetration; Tim-BOR excels in flexibility with dust or liquid forms.
- Monitoring integration: Bait station wood inserts support ongoing termite surveillance; visible foam and liquids provide rapid spot treatment.
- Finish compatibility: PenaShield dries to a natural wood look; many foams and dust formulations are designed to minimize staining on wood.
- Application ease: Ready-to-use liquids and foams are user-friendly for DIY, while monitoring inserts suit professional systems and existing installations.
- Scale and reach: Foams and liquids address active colonies and voids; wood inserts support broader monitoring across larger structures.
In summary, a layered approach—combining penetrating preservatives, targeted insecticides, and a monitoring program—offers a robust defense against termites and wood-destroying pests. Always follow label directions, ensure proper ventilation, and coordinate with local pest control guidelines for safe and effective results.
