We have lived here for almost 37 years and this is only the second time we've had a problem with sugar ants. The weather is very warm today-75-and every time it warms up, we have another invasion. I thought they were gone, sigh.
They are coming in by the patio door, so have some stuff that should take care of this gang soon.
I guess our mild winter has created quite a problem with the little critters.
