Brief description

A fly catcher is a simple trap that reduces flies by attracting them with bait and capturing them using a sticky surface or a one-way entrance.

Use / Function

Pest control: Reduce flies around food, animals, and waste.
Food safety: Lower contamination risk in kitchens and storage.
Hygiene: Improve comfort and reduce disease transmission.
Scale: Household, pantry, animal sheds.

Operating principle

Flies follow strong odors from sweet or fermenting bait. Once they land on a sticky surface or enter a narrow funnel, they cannot escape. Stickiness comes from Glue or Resin. Bait is made with Sugar, Water, and Vinegar or fruit scraps.

How to create it

Prepare bait: Warm Water and dissolve Sugar, add a small amount of Vinegar or fruit mash.
Make a sticky strip: Brush Glue or warmed Resin onto a strip of Paper.
Build a bottle trap: Place bait in a Glass jar and insert a cone of Paper with a small opening.
Hang or place: Use Plant fibers to suspend strips or set jars near fly paths.
Maintain: Replace bait and sticky strips as they dry or fill.

Materials needed

Essential: Paper, Glue or Resin, Sugar, Water.
Containers/structure: Glass jar, Wood frame, Plant fibers for hanging.
Tools: Knife, pot, brush.
Substitutes: Honey or fruit mash for bait, clay pot instead of glass, cloth strips instead of paper.

Variants and improvements

Flypaper ribbons: Long strips hung near windows and doors.
Funnel jar: Narrow cone improves one-way entry.
Covered bait cup: Small lid holes reduce dust and splashes.
Outdoor shelter: Simple Wood roof to protect from rain.

Limits and risks

Non-target insects: May capture beneficial insects.
Mess: Sticky surfaces attract dust and debris.
Odor: Fermenting bait can smell if left too long.
Weather: Wind and rain reduce effectiveness outdoors.
