Keep outdoor spaces and work areas more comfortable during fly season by replenishing your TERRO Fly Magnet trap with these ready-to-use bait packets. Each package contains 10 two-packs (20 total baits) formulated to create an attractive scent plume when mixed with warm water. Designed for use with TERRO T380/T382 Fly Magnet systems, these refills let you refresh the trap quickly so it continues to capture flies over repeated cycles.

How do I prepare and load a TERRO Fly Magnet bait packet?

Preparing the bait is straightforward and requires only warm water and your compatible Fly Magnet trap. Empty one packet into the trap reservoir, fill to the indicated line with warm water, then swirl gently to dissolve the bait. Allow a few hours for the scent to activate before expecting full trapping performance.

• Empty bait packet into the trap bowl or reservoir.
• Pour warm (not boiling) water up to the trap's fill line.
• Swirl to mix until solution is uniform; wait a few hours to activate.
• Place trap at ground level or hang in a warm, calm, bright spot.

What types of flies will these baits attract and trap?

The formula targets common nuisance flies typically found around homes, barns, and outdoor dining areas. It attracts house flies, barn flies, and bottle flies by producing an appealing scent that draws them into the trap. Once inside the Fly Magnet system, flies are unable to leave, allowing you to reduce visible fly activity in the treated area.

• Effective on house flies commonly found near homes and trash.
• Attracts barn flies often present around livestock and feed.
• Draws bottle flies that frequent decaying organic material.
• Works best when traps are placed where flies congregate.

How long does one bait packet remain effective and how often should I replace it?

Once mixed and active, each bait keeps attracting flies for an extended period without losing potency quickly. Activation typically takes a few hours after preparation; thereafter the bait continues to produce the attractive scent until the trap collects significant numbers of flies or the solution becomes heavily soiled. Replace or refresh the bait when the trap is full or when capture rates decline noticeably.

• Activation time: usually a few hours after mixing.
• Replace when the trap is visibly full of flies or debris.
• Refill traps repeatedly using the same reusable Fly Magnet container.
• One package provides 20 single-serve baits for multiple refills.

Where should I position the Fly Magnet trap for best results?

Placement influences catch rates: pick warm, well-lit, and relatively calm locations where flies naturally gather. You can set the trap on the ground near trash cans, compost, or animal areas, or hang it from a branch or hook about head height to intercept flying insects. Avoid placing the trap directly in windy corridors where the scent plume will disperse too quickly.

• Ground placement near waste, feed, or outdoor dining areas.
• Hang from a tree, stake, or hook for elevated coverage.
• Choose warm, bright, calm spots for consistent attraction.
• Keep away from windy areas to maintain the scent plume.
