These unsightly holes are a sure sign
that a caterpillar is merrily munching on this ornamental grapevine. To control
these pests all it takes is a simple spray of eco-neem. Just dilute it into a
good high pressure sprayer like this one and spray it thoroughly onto the
foliage. This certified organic insecticide is made from extracts of the
neem tree and is handy because it controls a broad range of chewing and
sap-sucking insects like grasshoppers, aphids, mites & whitefly. And best of
all eco-neem doesn’t harm beneficial insects like bees & lady beetles.
