considerable number have been with us in the Detroit area for 
a long time, and thru neglect, many people are losing valuable 
evergreens, because they do not recognize insect infestation in 
their evergreens until it is too late. The old adage “A stitch in 
time saves nine” was never truer than when applied to ever- 
green spraying. I will give you a list of just a few insects 
infesting evergreens in the Detroit area. 
RED SPIDER — This pest is probably the worst, because 
it is so widespread and attacks every kind of living plant. On 
evergreens it is especially destructive to blue spruces of all kinds, 
blue cedars and all types of red cedar. Tho not as bad, it does 
damage the arborvitas sume. The correct name of this pest is 
spruce mite, and like the plant lice it is a sucking insect. It 
seems to be especially damaging during hot dry weather. The 
insects infest the plants by the thousands and can be barely seen 
with naked eye. They suck the sap out of plants and destroy 
cells. Plants must be sprayed when they first appear, usually in 
late June and early July. Because the eggs are not affected with 
the spray, they must be sprayed three times, about five days 
apart. | 
JUNIPER SCALE — This is becoming very prevalent on 
Pfitzer and Sabina junipers all over this area. If not controlled 
it kills the plant in several years. We spray in May. 
JUNIPER WEB WORM — Common all over in Irish, 
Swedish and Meyer’s junipers. Spray immediately or there will 
not be any foliage left on your evergreens. This small worm 
bunches up the foliage with a fine web, and eats the foliage 
from the inside. 
PINE SAW FLY — This small worm works in colonies 
en pines, especially Mugho, Scotch, Jack and Austrian pines. 
They simply eat off last year’s foliage before the new foliage 
comes out. Call us immediately and we will stop their feeding 
before further damage is done. 
PINE SHOOT MOTH — This pest lives in and destroys 
the tip buds in pines and causes deformity. It prefers Mugha 
Pine and Scotch Pine in this area. Spraying must be done the 
last of June and early July. - -; .
