No, Demon WP would not penetrate into the wood to reach the powder post beetles.
BoraCare would be recommended to treat raw wood (no paint, stain/finish of any kind) for wood destroying insects such as powderpost beeltes and termites. Spray all sides of the wood, and if the wood is thicker than 5x5 inches thick, you would need to do 2 coats to make sure the product penetrates to the center of the wood, Boracare lasts for the life of the wood (indoors/protected from the elements) and will kill the beetles as they eat their way out of the wood and emerge, as well as protect it from new infestations down the road. View the BoraCare product label for more information.
You should still expect to see some activity of the beetles even after treating, as they only are killed through ingesting the treated wood, and you cannot stop/control when the life cycles try to emerge.
For smaller applications areas or if treating wood that is painted, stained or sealed, Jecta would be an alternative option. Drill holes iinto the wood where powderpost beetles have been observed and insert Jecta into the holes for direct colony treatment. This product will also absorb into the wood and then last the life of the wood. Same process as with BoraCare, as the insects consume the wood from the inside they will die from eating the treated wood. View the Jecta product label for more information.
Demon WP Insecticide is labeled for German roaches however will only kill roaches that come into contact with the treated area and does not have any transfer qualities which is important in eliminating an active roach infestation. This is not a contact kill and take 1-3 weeks to kill the roaches that have contacted the treated areas.
The best treatment for German Roaches as they reproduce quickly and in large numbers would be to use a combination of products along with diligent repeat treatments every 14 days.
Please view our Roach Control Kits and Roach Treatment Guide for more information.
Demon WP Insecticide should only be applied along baseboards and in cracks and crevices when used inside. When applied around hard floors be sure to avoid the edges where you apply when mopping or you will remove the product. If you applied across an entire floor you should mop to remove as soon as possible.
No Demon WP cannot be used for an in-home delivery system. For in-home delivery systems, you can use either Optigard Flex Liquid or Tandem Insecticide. Be sure to follow the product label for dilution and application rates.
Demon WP can be used on ornamental plants only (do not use on edible vegetation). You can find products safe for use under our Edible Garden category.
Demon Max is made by the same company that makes Demon WP and they both contain the same active ingredient just different formulations. The main difference is Demon Max can be used as a termiticide to treat and protect homes against termites and can be used for general pests. Demon WP is more for general insect control inside and outside homes.
