What is the difference between Delta dust and Drione dust? I want to kill brown recluse spiders.
Which one do you think would be better?
The main difference in these two products are the active ingredients. Delta dust contains the synthetic pyrethoid deltamethrin while Drione dust contains the natural ingredient pyrethrins. Both will do a fantastic job eliminating almost any insect including spiders, though you should note that dust insecticides can take several days to actually kill the insect. Delta dust does have one advantage over Drione dust, Delta dust is the only waterproof dust on the market and it will still be effective even if it gets wet.
