You would want to dust behind and underneath furniture, appliances, garage perimeter and inside wall voids. All dusts pretty much work the same way and all are OK on spiders. But the inherent problem is that spiders are hard to kill because they do not groom themselves. Unlike other insects that walk over dust, get it on their legs, and then groom themselves, spiders do not groom their legs and therefore do not ingest the dust as easily. For this reason, glue boards and sprays are typically used more often. We have a spider kit that is very popular for brown recluse spiders and all spiders in general that we would recommend.
