Bait Formulations and Selection
Different bait types (gel, granular, liquid, paste, block) and selection criteria based on target pest feeding preferences and application site.
Detailed Overview
Bait formulations designed for specific pest feeding behaviors. (1) Gel baits: for roaches and ants. Applied as small drops in harborage. High moisture content, attractive food base plus insecticide. Shelf life 1-2 years. Best for: crack and crevice application, indoor use. (2) Granular baits: for ants outdoors, crickets, earwigs. Broadcast or spot application. Weather-resistant. Best for: outdoor perimeter, turf, landscape beds. (3) Liquid baits: for ants, especially sugar-feeding species. Applied in bait stations. Best for: outdoor ant colonies, pharaoh ants indoors. (4) Paste baits: for rodents. Moisture content appeals to rodents without water access. Best for: attics, wall voids where dry. (5) Block baits: for rodents. Long-lasting in bait stations. Best for: exterior stations, long service intervals. (6) Soft bait packets: for rodents. Pre-measured portions. Best for: interior stations, situations requiring portion control. Selection criteria: pest species determines formulation - pharaoh ants prefer liquid, German roaches prefer gel, Norway rats prefer blocks. Environment matters: outdoor requires weather-resistant granular or blocks; indoor allows gels and pastes. Feeding behavior: protein vs carbohydrate preference guides bait selection. Rotate formulations quarterly to prevent bait aversion.
When to Use
Match bait formulation to target pest biology and application environment. Gel for indoor roaches/ants, granular for outdoor ants, blocks for exterior rodent stations, paste for interior rodent stations.
Required Skill Level
Requires some training and experience in pest management
Benefits
- Formulation matched to pest preferences maximizes acceptance
- Appropriate formulation improves efficacy
- Weather resistance when needed
- Precise application with gels
- Long-lasting with blocks and granules
Limitations
- Wrong formulation rejected by pests
- Some formulations inappropriate for certain sites
- Costs vary widely between formulation types
- Shelf life differs - gels dry out faster than blocks
- Must stock multiple formulations
