GREEVER’S 
SPRAY CONCENTRATE 
Containing 25% DDT 
This type spray is easy to use and makes an emul¬ 
sion by stirring with water giving an even application 
of DDT. It is recommended to be used in dairy barns 
and other outbuildings; also around the outside of 
dwelling houses where a slight residue is not objection¬ 
able. It kills flies, fleas, lice, ticks, mosquitoes, roaches, 
silver fish, and many other insects. As this spray con¬ 
tains a small amount of oil, it is not advisable to make 
heavy application to the skin of animals, although it 
may be used to a moderate degree without injury. 
This type of spray is especially recommended for 
spraying shade trees and many ornamental shrubs for 
killing insects that injure the foliage—as evergreen 
bagworm, catalpa sphinx, boxwood leaf miner, gypsy 
moths, saw flies, elm leaf beetles and others. For this 
purpose, it is used in a dilution of one pint of spray to 
25 gallons of water, making an economical way to rid 
your ornamentals of insect pests.
