This is poison I put out. It must be sweet because they found it right away. After not very long, the entire colony was out there. Their colony is in the attic. There is a tiny whole by the ceiling that they came and went from.
You could see them all coming and going from the hole to the poison taking it back to the colony. Hopefully it works and they are gone!
I don't think this is the end of the bug problems we are going to have. With the house being empty all spring and summer and the amount of spiders that were in the back yard it isn't going to be pretty.....
