I was getting ready to have some seeds go into my square foot garden (raised beds) when I noticed one corner of one of the raised beds has become an ant bed. It hasn't mounded, but I think the bed is an extension of one I noticed to the side of SFG raised bed. I have four SFG beds, each 4X4, and all on a concrete pad; the mound is just off the pad.

I was pulling a weed and in doing so disturbed the soil and also disturbed several hundred ants. With a stick I did a little more stirring and one entire corner (nearest the mound) is filled with thousands of ants. If the type of ant matters, I took a photo, which can be seen he

I need to get the ants out of the bed without having them just move next door to the neighboring bed, and hopefully do so fairly quickly. Any thoughts?

Thanks,
