    Q
    Will Demon WP Insecticide kill June bugs?
    We have horrible June bug problems and I hate them.
    A

    Demon WP will kill any june bugs or beetles that land on or crawl over a treated surface its been applied to. June bugs and other similar pests like Japanese Beetles, are part of the grub life cycle. The best way to prevent June bugs and beetles is to treat for grubs twice a year to control as many as possible before they emerge from the soil and complete their life cycle as a beetle. You can review our Grub Control Guide to see the best products and timing for treating the yard and reducing the overall numbers that you may have to take care of with the Demon

    Q
    What kind of IGR should I use with Demon WP to treat for carpet beetles?
    I have a carpet beetle infestation and have just started using Demon WP today to help with this issue. Two exterminators have used their products in my home within the past 3 weeks. They claim to have used an IGR but now I'm concerned that I should also use an IGR now that I've taken over handling the exterminating. If so, which kind should I use in conjunction with the Demon WP?
    A

    Demon WP actually is not labeled to treat for carpet beetles indoors, but it will help to combat a variety of other pests listed on the product label. A great IGR for carpet beetles would be Gentrol IGR. You can mix this concentrate with an insecticide and apply them at the same time. A great choice for insecticide to use with Gentrol as a crack and crevice treatment would be Suspend SC, which is a liquid concentrate. Be sure to vacuum thoroughly and often when treating for carpet beetles to help pick up adults, eggs, and debris that they may feed on such as animal dander.

  • Asked by Phill from Silverdale, Wa
    08/17/2017
    Q
    Can you mix Demon Max and Demon WP?
    A

    There is no valid reason to mix Demon Max and Demon WP together.  Demon Max is a synthetic pyrethroid and Demon WP already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

    Is Demon WP a good substitute for Cynoff WP?

    Q
    What happens if an animal comes into contact with Demon WP before it has dried?
    A

    Animals should always be kept out of the area where Demon WP is being applied until the area has completely dried.  If you think that a pet or other animal has come into contact with a treated area that is still wet, it would be best to contact the manufacturer directly for advice on what action should be taken.  You can reach Syngenta by calling 866-796-4368.

    Q
    How often do you have to reapply Demon WP Insecticide to kill infestation of carpenter ants in an oak tree?
    A

    We normally would not recommend to use Demon WP Insecticide for carpenter ants. Although, it will kill the ants that contact it, it will not eliminate the colonies. 

    We generally recommend using Dominion 2L for carpenter ants in trees. This can be used directly on the tree or as a soil drench.

    Also, please check out our Carpenter Ant Guide for tips on how to treat and prevent carpenter ants.

    Q
    Is the Demon WP the best product to use indoors for "crazy" ants?

Crazy Ants may also nest inside rotting wood and tree holes. You can read our article on crazy ants for more treatment information: How to Get Rid of Crazy Ants.
