What kind of damage can insects cause?
Depending on the type of insect, they can cause anything from the munching of a few leaves to the death of an entire oak tree. Caterpillars only eat the leaves of a few select plants based on the species, Scale sucks the life out of a palm, and Bore worm destroys the mighty oaks. However depressing this may sound, only a tiny 1% of insects are actually pests. Of course, you may not think so, but you usually take notice of only the bad bugs that you constantly fight rather than noticing the good bugs that stay in hiding. This means that 99% of insects are helpful, so think twice before spraying and make sure that you are killing the bad guys and not the good ones.
