USE CYANOGAS A-DUST TO KILL 
PESTS IN THEIR BURROWS 
CYANOGAS A-DUST is a fine powder, 
used world-wide, to kill all burrowing 
pests—ANTS, RATS, MICE, WOOD- 
CHUCKS (Groundhogs), MOLES, 
GROUND SQUIRRELS, GOPHERS 
PRAIRIE DOGS and other similar in- 
sects and rodents. 
CYANOGAS is automatic and complete 
in its effects — does not single out one 
rodent. All are KILLED INSTANTLY 
WHEREVER THEY MAY BE. 
Shallow rodent burrows, such as wood- 
chucks (groundhogs), can be treated by 
inserting CYANOGAS down the en- 
trance with a long-handled spoon. Best 
results will be obtained 
in deep burrows by 
blowing a cloud of 
CYANOGAS into the 
burrow or hideout 
with a duster. 
WA RODENTS can keep 
ae PESTS clear of baits and 
i gee traps—they can’t escape 
from CYANOGAS. 
The CYANOGAS FOOT PUMP 
DUSTER is specially designed for apply- 
ing CYANOGAS A-DUST. Ruggedly 
constructed, lasts indefinitely. Price $7.00.
