Think before you spray!
Many beginner gardeners panic at the sight of the least insect. A common attitude is “Quick! Where is the most powerful insecticide I can find to blast that bug to smithereens?”
The wise gardener takes a few minutes to look over the situation. After all, the vast majority of insects are either innocuous or somewhat to very useful. Only about 10% are actually harmful in any way. Before you start to spray something noxious in your garden, take a few minutes to look into what’s going. The insect you’re about to destroy is perhaps one of your garden’s best friends!
Consider the following: if the insect does not appear to be eating your plant and does not seem to have a probiscus that pierces the stem, there is normally no reason to chase it away and certainly not to poison it.
