I have white-footed ants in my attic and I would like to dust the attic to help control or eradicate the colony. It seems that both orthoboric acid dust and diatomaceous earth are effective ant killers. Since they work differently, would you recommend making a 50/50 mixture of the dust and then using that mixture to dust the attic?
It is not necessary to mix the dusts together. We would recommend using diatomaceous earth inside the wall voids and cracks and crevices if the white footed ants are there. If they are in soil, mulch and under items, we would recommend you treating the colony using Suspend SC. You will use 0.25 fl. oz.-0.75 fl. oz. per gallon of water. Suspend SC will provide a residual that lasts for up to 30 days. Please let us know if you have any additional questions.
