Demon WP Insecticide can safely be used on shrubs.
Demon WP is not really selective, so unfortunately it is possible that butterflies or bees could be harmed if they were to come into contact with a treated area. To minimize this risk, it is recommended to apply in the early morning or in the evening when these insects are least likely to be foraging, and not to apply to any flowering vegetation.
While Demon WP Insecticide will kill carpenter ants, it will not allow you to kill the colony, which is necessary to eradicate a carpenter ant infestation. Our Indoor Ant Kit contains the necessary products to eradicate an entire colony of carpenter ants indoors. Please take a moment to review our How to Get Rid of Carpenter Ants Guide for great information on getting rid of carpenter ants.

Depending on the size and health of the fly and the amount of Demon WP it contacts, it generally would take anywhere from a few minutes to several hours for an insect like a fly to die after contacting an area treated with Demon WP. For a very quick kill for flying insects, we recommend Maxforce Fly Spot Bait or Alpine Pressurized Fly Bait.
Demon WP is not labeled to control pantry pests, although it would likely kill any that contacted it. For the best control of a stored product pest such as the red flour beetle, it is really essential to keep looking for and to locate that initial source to get full control of the infestation. You can then vacuum and clean infested areas, treat cracks and crevices with a residual insecticide, and use traps for the adult insects. Gentrol Complete is a great spray to use since it includes both insecticide and Insect Growth Regulator (IGR) in one product. You can use GreenWay Pantry Patrol Traps for a pheromone trap.
Demon WP Insecticide cannot be used inside the home for fleas, only outdoors as directed on the prouct label. Fleas treatments with approved products are generally done every 2 weeks with lots of vacuuming in between.
