Garden Pests and Diseases: termites?, 0 by tropicalaria

Last spring I built a raised bed for my bamboo and sided it with limbed branches from one of the trees I cut down. It made a nice rustic effect and I had considered doing the same edging for another raised bed I was building this year.

This morning while I was looking over the plants I found a swarm of flying insects around one end of the bed, in the shade. Because there isn't anything to eat there (nothing planted on or around that end yet) I went to investigate. These are what I found. Because they moved so quickly it was hard to snap a good picture. Are they termites? And if so, how do I get rid of them?
