Preliminary Evaluation of Commercially Available
Filth Fly Traps

• CDR Daniel Szumlas and Dr. Todd Walker Navy

  Florida
• Dr. Chris Geden and Dr. Jerry Hogsette
• CMAVE, USDA Gainesville, FL

4
Filth Fly Problem Situations

• Sanitation is the most important factor in fly
  control
• Sanitation levels can be modified where adult
  flies feed and larvae breed
• On Camp - mess halls, latrines, dishwashing
  areas, soakage pits, garbage handling areas, burn
  pits

5
Filth Fly Problem Situations

• Problem Areas Sites off limits
• Outside the camp villages and villagers w/
  unsanitary habits or domesticated animals,
  landfills, sewage treatment facilities, etc.

6
Fly control options when source reduction
sanitation levels are beyond our control?

• Exclusion
• Pesticides
• Pesticides may be limited and
• Flies develop resistance quickly
• Trapping is a viable option as part of management
  program

7
Fly Traps for Evaluation

• Objectives
• Test traps with potential for use in long-term
  control program
• Re-usable or with large capacity
• Ready easy to use bait provided, just add water

Trap placement

• Site conditions affect trap catch drastically
• Wind, sun exposure, temperature, flight paths,
  distance from and to breeding/resting/feeding
  sites

25
Trap placement

• Traps were placed equidistant from each other and
  from closest available source of flies.
• 10 ft apart 2 ft from ground rotated daily, for
  7 days

• Flies and debris collected in ziplock plastic
  bags
• Sorted as either House flies or Blow Flies
  (Calliphorid/Sarcophagid)
• Counted

Introduction

• Good Afternoon, Welcome to the filth fly
  symposium
• I am CDR Szumlas, from NEC Jax, along with
• Dr. Jerry Hogsette from CMAVE USDA Gainesville
• Moderate this session on filth fly biology,
  ecology, and control strategies.
• On deployment, SOMETIMES there are vector borne
  diseases
• ALWAYS flies
• The ORDER OF TOPICS was loosely put together as a
  field scenario where
• On deployment, a source of flies is emerging from
  a dog or camel carcass or garbage or feces up the
  road
• whats going on there, ESPECIALLY THE CARCASS
• Got Flies, want to control them using trapsWHAT
  ARE THE BEST TRAPS?
• IN DESERT ENVIRONMENT OF IRAQ, AFGHAN. What
  factors are important in filth fly attraction and
  control in desert environments
• WANT TO USE PESTICIDES
• Finally, What are the new baits, traps and other
  fly control techniques that show promise for the
  future?

41
Conclusions Still need answers

• Can we control flies with enough traps,
• To what degree control?
• How many traps do we need?
• 1 trap/30 linear ft of breeding/feeding area
• Is new bait needed each week?
• How long will these traps work without new bait?
  For what fly species?

Conclusions
51
Successful fly trapping

• Use 1 baited trap / 20-30 ft. around perimeter of
  fly breeding area, or where flies rest in
  morning/afternoon
• House and blow flies strongly attracted to odors.
  Baits can be made for
• House flies
• Water
• Grain
• Molasses
• Milk
• Bananas
• Blow flies Odors of decaying eggs and meat e.g.,
  fish

Still need answers

• For long-term control, how does succession fit
  into this equation?
• After 1 week, are dead flies/old fluid attractive
  to house flies, or only to blow flies not
  necessarily attracted to our food?
• Is new bait needed each week?
• How long will these traps work without new bait?

Problems with traps

• Not used/attempted often enough to know if
  control achieved,
• labor intensive, trap emptied, bait replaced
  weekly
• messy,
• disposable traps expire or fill up,
• must be replaced

67
Fly Trap Types

• Disposable vs. Reusable (jar vs. bag)
• Trap geometry/design Fly entry
• Top (holes)
• bottom (cone),
• Side hole and tube,
• both top and bottom (for chimney effect)
• Ready-to-use (just add water) vs. provide your
  own bait mixture
• Commercially available vs. you build it (e.g.,
  Pyramid/Cone trap)
• Trap
