Buying Guide
- Target pests: Choose products labeled for termites, carpenter ants, and carpenter bees, with outdoor tree and root-zone coverage for best results.
- Application method: Consider spray nozzles and ease of use (crack-and-crevice vs. broad-spray). Vertical trunks and root zones often require precise application to minimize drift.
- Residual protection: Look for products with long-lasting residuals to deter reinfestation around trees and wooden landscape features.
- Indoor vs outdoor labeling: For trees, outdoor labels with trunk and soil-near wood protection are essential to prevent wood-destroying insects from climbing the tree.
- Safety and compatibility: Verify compatibility with non-target plants, beneficial insects, and pets. Follow label directions for safe use around gardens and grounds.
- Environmental impact: Use targeted applications and avoid overspray into water sources or dense flowering vegetation to minimize ecological effects.
- Cost and coverage: Larger-volume concentrates may be more economical for larger properties, while ready-to-use aerosols offer convenience for spot treatments.
