Don't be alarmed if you find insects on your plants. These little unwanted guests sneak up on you when you're not looking and build huge populations before you notice that they're even there. And they feed ferocious appetites by feasting on your favorite plants!
In nature plants and insects live together. Wind, rain, and natural predators (other insects) keep populations in check. Because these natural barriers aren't present in your home, a perfectly healthy plant that looked great yesterday can be covered with creepy crawlers today.
