Any creepy crawly thing with six legs is an insect. They share similar life stages, going from egg to larva to adult. Of course, from your point of view, spiders are bugs, too, even though they're not insects, but arachnids.
That beautiful lawn of yours makes a great home for all sorts of bugs. Ticks, spiders, weevils and other creepy crawlies hang out there. You can make them go away by applying specialized lawn treatments, such as Ortho® Bug B Gon MAX® Insect Killer For Lawns.
When bugs are active, use a spreader to apply a bug control, such as Ortho® Bug B Gon MAX® Insect Killer For Lawns. Different insects require different concentrations, so check out the directions for what's in your lawn.
Many of the same bugs that love your lawn also take a fancy to your shrubs and flowers. You can treat them with a spray product, such as Ortho® MAX® Flower, Fruit & Vegetable Insect Killer Ready-To-Use.
