Here's something new. Right where my deck meets my siding (two corners) I have all these teeny tiny little bugs. They look like the head of a pin. On interesting characteristic is as soon as I get close to them, they start hopping and jumping around. Very strange.

What the heck are these things? Do I need to call in an exterminator, or are they harmless and can I just hose them off or use some Raid or something?
