CYANOGAS 
KILLS ANTS INSTANTLY! 
Ant nests can dangerously disturb root systems. 
Ants themselves are the “caretakers” of certain de- 
structive insects such as aphids and mealy bugs. Pro- 
tect your lawns and gardens with CY ANOGAS. 
A small quantity of CYANOGAS injected into 
the ant nest evolves a gas which penetrates quickly 
throughout—killing all ants present. They need not 
eat or even touch it. 
Do not use CYANOGAS indoors. If ants are 
found in the house trace the line of foragers back to 
their nests in the soil. 
To apply CYANOGAS most effectively probe the 
nest with a thin stick or screwdriver to about 6 or 
8 inches. Adjust spout to can— 
allow about as much CY ANO- 
GAS as can be held on a dime 
to flow into the open hole. 
Then close hole with dirt. 
CYANOGAS is also sold in larger 
containers at lower prices. Ask your 
dealer for literature giving instructions 
for control of pests other than lawn and 
garden ants.
