SHINER CACTUS NURSERY 43 
Stapelia gigantea 
INSECT CONTROL 
A recommended spray for killing all pests on cacti and other succulents is 
mixed as follows. To a quart of denatured alcohol add gradually about one table¬ 
spoonful of a fly spray such as Ocedar. The spray is shaken up with the alcohol 
and only as much is added as will dissolve. Use small sprayer. Two sprayings 
about a week apart should get all pests and their eggs,—scale mealy bug, all 
types of aphis and Red Spider. 
When you have scale on your plants look for ants and get rid of them. 
When you find mealy bugs examine roots of plants. If found there soak 
with a solution of Black Leaf 40 two or three times at weekly intervals, in addi¬ 
tion to spraying the plants. Use a weaker solution for spraying seedlings 
and succulents than for thicker skinned plants.
