Ack! Some sort of white ugly bugs in my onions! [View all]

[Aerows]

Dad says they are termites. I hope they don't take over the whole garden. My cuke plant's leaves are turning yellow even though it is producing huge cucumbers, and I had a bell pepper that turned black on one side, even though it was getting big.

What on earth do I do?

There are HORDES of these little white looking bugs with the density of ants at the roots of my onions.
