Gel Baiting
Targeted application of gel-formulated insecticide baits into cracks and crevices where cockroaches and ants live and travel.
Detailed Overview
Gel baits are applied from a syringe or tube in small placements (pea-sized drops) in harborage areas like cabinet edges, appliance voids, wall voids, and plumbing penetrations. Pests consume the bait and return to harborage areas where they die, often exposing other pests through coprophagy or cannibalism. Gel baits are the standard pesticide technology for cockroach and ant control in IPM programs. They are odorless, non-volatile, produce no airborne particles, and allow residents to remain in treated areas. Placements should be inspected periodically and replenished as consumed. Gels should never be applied to exposed surfaces that could contact food.
When to Use
First-line pesticide treatment for cockroaches and ants after HEPA vacuuming and sanitation. Apply to harborage areas identified through inspection and monitoring. Reapply as baits are consumed.
Required Skill Level
Should only be performed by licensed pest management professionals
Benefits
- Highly effective for cockroaches and ants
- Minimal exposure to residents and pets
- Can be applied while residents are present
- Targets pests in harborage areas
- Secondary kill through bait sharing
- No preparation required (no need to remove food or dishes)
Limitations
- Requires professional application
- Baits may dry out or become soiled over time
- Some pests may avoid baits if other food is available
- Must be reapplied periodically
- Cannot be used as only treatment method

Non-chemical pest removal using High Efficiency Particulate Air (HEPA) vacuum cleaners to physically remove pests, eggs, droppings, and allergens.
Steam Cleaning
Non-chemical pest control using high-temperature steam to kill pests, eggs, and larvae on contact.
