Birth of Young 
Che Gascinating Praying NHantis 
A Garden Dinosaur Who Destroys the Bugs That Would Eat Your Flowers 
In spite of its fierce appearance and bloodthirsty habits 
the Praying Mantis is harmless to man. In fact, its insatiable 
appetite for beetles and the thousand and one pests a garden 
is heir to make it a valued friend to the farmer and gardener. 
The insect also makes an engaging pet. It will cling to a 
house plant or a curtain for hours at a time without moving 
more than a few inches. By feeding them bits of hamburger 
or corned beef on the end of a toothpick you can keep them 
alive inside for weeks. But they thrive better on a diet of 
insects found outdoors anywhere in the garden. The Praying 
Mantis stands zero temperatures without injury. It has 
spread along the New England Coast and has established itself 
in parts of Illinois as well as around Rochester, New York. 
Scientists who have studied it for years believe it can be 
introduced anywhere south of the Great Lakes, including 
southern Michigan. Statistics compiled by Dr. Henry Fox, 
formerly of the U. S. Bureau of Entomology, reveal that the 
number of young Mantis coming from a single egg case run 
from 125 to 350. We furnish the egg cases attached to a 
small 8-inch stick, as shown in illustration, which you can 
tie on to any shrub outdoors. 
Egg cases are mailed from January 1 until May 1. 
Order at once, please! $1.50 each. Mailed free in strong 
carton.

Mantis read Grassroot Jungles, price $3.75.

INSECTICIDES and FUNGICIDES 
ANTKILLER OR BAIT 
LETHELIN JELLY 
For quick, permanent relief from Ants, 
Roaches, Silverfish. A clean, odorless ant 
bait, packed in handy tubes for your con- 
venience. It does not melt or run at ordi- 
nary temperatures. The 3-ounce tube, 85c; 
8 ozs., $1.75. 
HOW IT WORKS 
Ants’ taste is so keen, they quickly de- 
tect usual poisons and stop feeding before 
the colony is destroyed. The slow-acting 
toxic ingredient in Lethelin Jelly is taste- 
less, but combining it with attractive ele- 
ments makes them prefer it to their favor- 
ite foods. They eat it greedily and live 
long enough to carry it to their nest to 
feed the queen and young, wiping out the 
whole colony.
