Little teeny red bug looking things?

Most likely they are spider mites which are common plant pest in your area from late spring to mid fall. They are only worried about sucking the blood from your plants so you don't have to worry about them bugging you too much. They are bug to kill, but it's best that you get rid of them as they can take over (they are probably being kept down by those monthly sprayings) I would go and get something from yo local nursery and spray about every other day. If you have anything sensitive or edible, I would take a mild soap(like laundry detergent) water, and if you have a juicer or food processor some garlic(pulverize the garlic you really only need the juice or oil, the garlic is optional) and spray your plants everyday with this mixture.(one part soap to about 4-5 parts water)
