House fly is a major pest, essentially everywhere.

Plenty of house fly traps to choose from!

Hanging toxicant deviceSticky trap on post

Box trap Bag trap

Hanging plastic bag with water trap

So which type of trap is best for which situation?

2 Wet traps

Captivator

1 Sticky trap

E Z Trap

Fly Relief

Golden Malrin &Blue Streak Scatter Baits

QuikStrike & QuickBayt Bait Strips

Bait strips placed in buckets of sand

Scatter baits placed on trays

1. The 7 traps/baits/bait strips were rotated through 7 sites.

2. The traps/baits/bait strips were left at each site for 24 hours, then flies were counted.

3. Study was replicated 3 times.

Captivator

The wet jar trap captured significantly more flies than the other devices.

Mean number of flies = 704.29(±125.02)a

Fly Relief

The wet bag trap captured significantly less flies than the wet jar trap, but significantly more flies than the remaining devices.

Mean number of flies = 583.33(±117.70)b

E Z Trap

43.71(±7.87)c

32.52(±3.46)c

17.57(±5.43)c

4.67(±0.60)c

1.05(±0.38)c

Mean number of flies

No significant difference in mean numbers of flies captured by remaining devices.

Captivator

Current recommendation under desert conditions would be to use traps containing moisture.

Fly Relief

Scatter baits and bait strips may be more effective is flies have access to water nearby.

Future Plans

1.Return to Cairo in April.

2. Measure temperature changes inside the wet traps as an indication of trap efficacy.

3. Alter presentation methods for scatter baits and bait strips.
