tion of overripe bananas with milk is much more attractive than 
either one used separately. A considerable number of blow-flies 
as well as house flies are attracted to such baits. 
BAIT CONTAINERS. 
The size of the bait container in relation to the size of the trap 
is a very important consideration. It has been found that a small 
pan or deep pan of bait set in the center under a trap will catch 
only a small fraction of the number of flies secured by using larger, 
shallow containers. The best and most convenient pan for baits is 
a shallow circular tin, such as the cover of a lard bucket. Its diam- 
eter should be about 4 inches less than that of the base of the trap, 
thus bringing the edge within 2 inches of the outside edge of the 
trap. The catch can be increased slightly by placing a piece of 
sponge or a few chips in the center of the bait pan to provide addi- 
tional surface upon which the fhles may alight. The same kind of 
pans for bait may be used under tent traps. Two or more pans 
should be used, according to the length of the trap. 
CARE AND LOCATION OF TRAPS. 
In many cases fly trapping has been rendered ineffectual by the 
fact that the traps were not properly cared for. In setting traps 
a location should be chosen where fires naturally congregate. This 
is usually on the sunny side of a building out of the wind. It is 
exceedingly important that the bait’ containers be kept well filled. 
This usually requires attention every other day. The bait pans 
should-be washed out at rather frequent intervals. This gives a 
larger catch and avoids the danger of flies breeding in the material 
used for bait. - Further, it should be borne in mind that traps can 
not be operated successfully throughout the season without emptying 
them. Where flies are abundant and the bait pans are properly 
attended to the traps should be emptied at weekly intervals. Where 
flies become piled high against the side of the cone the catching 
power of the trap is considerably reduced. The destruction of the 
flies is best accomplished by immersing the trap in hot water, or still 
better, where a tight barrel is at hand place a few live coals in a 
pan on the ground, scatter two tablespoonfuls of sulphur over them, 
place the trap over the coals, and turn the barrel over the trap. 
All of the fiites will be rendered motionless in about five minutes. 
They may then be killed by using hot water, throwing them into 
a fire, or burying them. 
STICKY FLY PAPERS. 
Sticky fly papers are of some value in destroying flies which have 
gained access to houses, but they have marked limitations and num- 
erous objectionable features. For use out of doors, traps are much 
more effective and economical.
