Buying Guide
- Active ingredient and pest target: Look for dusts with cyfluthrin or deltamethrin for broad-spectrum effectiveness against carpenter bees and related pests. Confirm the product’s label includes carpenter bees or wood-destroying pests if that is your primary concern.
- Application method: Ready-to-use dusts are convenient for spot treatment in voids and cracks. A hand duster or injector helps reach deep crevices in wood and eaves, enhancing coverage where bees nest.
- Outdoor durability: Weatherproof or waterproof formulations help maintain efficacy in exposed areas. Consider products that advertise long residual protection when used outdoors.
- Safety and placement: Use dusts in well-ventilated outdoor spaces and inside voids away from children and pets. Follow label directions for safe application in wooden structures, attics, and soffits.
- Coverage and reapplication: Some products cover large areas per pound, while others focus on targeted application. Plan for reapplication cycles based on activity level, weather, and prior bee presence.
- Multi-pest effectiveness: If you face multiple pests beyond carpenter bees, choose a broad-spectrum dust with proven activity against ants, roaches, and spiders in addition to wood-infesting insects.
