   Coffee: Save leftover coffee to spray plants that have a problem, make sure to spray underneath the leaves as well as the stems and surrounding soil. You can also sprinkle a layer of used coffee grounds around the plant to ward off these pests. They won’t like it and will likely move on to greener pastures in a few short days.

Vinegar & Water: Pour 1 cup household vinegar and 1/2 cup water into a spray bottle. Spray the critters on the ground as you see them, but be careful not to spray the leaves of plants since the vinegar & water will damage them.

if you're not too tender hearted, put salt all over them and around the area where they hang out by your door. Try isopropol alchohol, too.
