I read that it is necessary to alternate insecticides to prevent resistance, but I was wondering how often that needed to be. Can I use Demon every other time I spray or less than that?
Demon WP Insecticide is a great product but yes, it is always a good practice to alternate products with different active ingredients. Resistance can take a few years to become an issue but you can switch between chemicals every 30 days, on a yearly or two year basis, no longer than that, to avoid any issues.
