Bottle fly trap - Kenya
Practical Action
Points in construction:
The lower bait bottle should be
opaque. This can be done by painting
it black or plastering it with mud.
Keep the inner tube the right size with
rubber bands while wiring the bottom
to the bait bottle. The holes at the
upper end should be quite small.
Positioning the bottle. It is best hung
just off the ground in the shade.
Bait. In Kenya goats droppings and
cows urine have been used. Flies also
favour the morning urine and stool
from a small child. Sour milk can be
used.

To make the tube inside the catch bottle, a
piece of plastic (roughly 8cm by 8cm) can be
cut from the body of another bottle. Small slits
need to be cut in the bottom and bent out as
shown in the diagram to make a ‘frill’. Roll the
plastic around a pencil, wrap a piece of string
An alternative, and perhaps simpler, method of
making and fixing the tube © TALC, 2005.
