CYANOGAS (Calcium Cyanide). G. 
Fumigant. When exposed to natural 
atmospheric moisture, Cyanogas liberates 
a gas which has proved to be the most effec¬ 
tive insecticide ever developed for many 
purposes. The gas is exceedingly penetrat¬ 
ing and easily kills breathing insects in any 
space where the gas can be confined. Thus 
Cyanogas is different from ordinary insect 
powders or sprays where the killing power 
is generally dependent on actual contact 
with the insect. Destroys aphis, white fly, 
soft scale, thrips, etc. 5 lbs. $3.00; $10.00
