In Belgium it was suggested to burn camphor over oharcoal or 
place a piece of camphor on a hot iron to fumigate flies .--Anonymous 
(U). 
The fumes stunned mosquitoes in 4 to 5 minutes and killed them 
in 4 or 5 hours.— Celli and Casagrandi (82, p. 95). 
Adult silverfish were killed by the vapors in a confined space, but 
bits of camphor soattered among papers or in book shelves did not 
keep them away.— Cornwall ( 106 , p. 121) • 
The larvae and eggs of the clothes moth Tineola biselliella (Hum.) 
oan be killed by placing oamphor or naphthalene in closed places.— 
Benedict (64). 
Camphor was ineffective against bedbugs, cockroaches, clothes 
moths, and carpet beetles* Naphthalene and camphor prevented infesta- 
tion of clothing by Attagenus pioeus (Oliv.), and killed all stages 
of the beetle, though the aotion of oamphor was very slow.— 
Scott and ooworkers ( 361) • 
Camphor-oil byproduct plus bonemeal was oonsidered one of the 
best repellents against the screwworm. There was no emergence of 
flies from meat treated with camphor oil.— Parman and coworkers (302 ) . 
To destroy body lice in military camps apply a mercurial oint- 
ment of camphor oil.—Beaulieu and Maheux (52, p. 175). 
There are at least 26 patents which describe the use of camphor 
as an insecticide or insect repellent.— Roark (333 , 335 , 346 ). 
Gum oamphor, used in the manner recommended for naphthalene and 
paradichlorobenrene, will kill all stages of the clothes moth. While 
it does kill some eggs and larvae when sprinkled upon infested cloth 
in open containers, it is not to be depended upon except where the 
fumes can be closely confined with the clothing.— Back (44). 
CINNAMOMOM CASSIS Blume. 
Oil of cassia exhibited good repellent action against the sorew- 
worm for 1 or 2 days only.— Parman and ooworkers (302 ) • 
Oil of cassia was moderately repellent to cockroaches.— Cole (101 ) . 
CINNAMOMOM ZEYLANICUM Nees. Cinnamon. 
Cinnamon oil was considered one of the best repellents against 
the screwworm. There was no emergence of flies from meat treated with 
it. Cinnamon powder was effeotive for only 2 days.— Parman and 
coworkers (302) •
