Enlarge entrances of nest 
and inject a small amount 
of CYANOGAS A NT KILL¬ 
ER. Close hole with dirt. 
The deadly gas liberated 
destroys the colony and 
kills the Queen deep in the 
nest. The 4-oz. can con¬ 
tains enough to kill a mil¬ 
lion ants—30c. 
Use CYANOGAS G-FUMI- 
GANT, scatter it over the 
greenhouse walk and close 
the house for the night. 
One cent more pays for the 
cost of fumingating 1,000 
cubic feet. Ask for “CY¬ 
ANOGAS HANDBOOK FOR 
GREENHOUSES AND 
NURSERIES” — contains 
complete directions. 
While rats keep clear of 
baits and traps they can¬ 
not escape from CYANO¬ 
GAS. This makes CYANO¬ 
GAS the perfect rodenti- 
cide. Widely used through¬ 
out the world by farmers, 
warehousemen. Health De¬ 
partments, Government 
Agencies, etc., etc. 
Thrips, bulb flies, and all 
bulb-infesting insects, 
yield to CYANOGAS. Does 
not rot the bulb, but has a 
stimulating effect. Can be 
used any time after bulbs 
are dry. 
Apply CYANOGAS to bur¬ 
rows of “dog towns,” using 
a long-handled spoon. The 
gas liberated from CYANO¬ 
GAS will reach all parts of 
the burrows and kill all 
prairie dogs that get a 
whiff. Not recommended 
for use in the Spring. 
Nothing is surer, quicker 
or more economical for 
mole control than CYANO¬ 
GAS. Every 10 feet along 
the runways make a hole 
and pump in the powerful 
CYANOGAS A-DUST. Treat 
the entire runways at one 
time. Complete instruc¬ 
tions with every can. 
INSECTS 
All soil, unless treated, is 
infested with numerous 
species of soil insects, such 
as wireworms, millipedes, 
symphilids, sow bugs, bugs, 
grubs of imported beetles 
and nematodes. Fumigate 
the soil with CYANOGAS 
to kill these pests. 
Mix CYANOGAS G-FUMI- 
GANT with the seed in an 
old milk can, empty drum, 
wooden case, churn or some 
other device. Use about Vz 
oz. to a bushel of seed. CY¬ 
ANOGAS liberates a gas 
which destroys all insect 
pests.
