  • Asked by Albert from Nj
    07/21/2015
    Q
    Can PT221L be sprayed down the drain where springtails appear in the sink?
    Springtails are appearing in my tub and sink. They may be coming from my septic tank.
    A

    PT 221L cannot be sprayed down drains. Springtails would not be coming from the drains unless there is a crack somewhere in the pipes that allows them to get in.  Most times people see springtails coming out of the drains after they are just gone down to get moisture. Springtails indicate that there is a moisture issue because they breed in walls or under slabs where a moisture issue may exist.  Typically, pesticides alone will not take care of a springtail problem.  It is required to fix whatever moisture issue is causing the problem. Please view our article "How to get Rid of Springtails". This article contains everything you need to know to treat for springtails.

  • Asked by Barry from Portland, Or
    08/08/2016
    Q
    Is PT 221L considered a non-repellent spray?
    If used in an area where house ants may enter (but are not yet present) will it cause the colony to bud when ants contact the treated area?
    A

    PT 221L Residual Aerosol - 17.5 oz. can would not be considered a true repellent to keep insects out.  It would only be slightly repellent for a few days after application.  Instead it is meant to provide a long residual to continue to kill insects that contact a treated surface.

    A

    PT 221L Residual Aerosol is labeled for bed bugs. This can be used on the tufts and seams of the mattress every 10-14 days. We would not recommend this being the only thing you are using for a bed bug treatment. One of our Bed Bug Kits is a great option for use in your home.

  • Asked by Dave from Nj
    02/11/2016
    Q
    Does PT 221L Residual Aerosol kill hornets and wasps?
    A

    PT 221L Residual Aerosol is labeled to kill wood wasps, but not hornets. This is a non-selective insecticide (lambda-cyhalothrin), so it would affect these insects if you were able to contact them, however it does not offer the quick knockdown that would be preferred for flying, stinging insects. We do sell an excellent Wasp and Hornet Control Kit which contains the ready-to-use Wasp-X and Temprid SC. The Wasp-X will have a fast kill than something like the PT 221L, plus it has a unique foaming action to expand and cover nests and residual activity. Temprid SC is a liquid concentrate that is diluted with water and applied with a pump sprayer in areas where insects may be likely to enter the structure.

    Please see our Wasp Pest Guide for more tips and information about this pest.

  • Asked by Angela from Mission, Tx
    03/24/2022
    Q
    Does PT 221L Residual Aerosol work on German Roaches as a residual spray? Can I used this along with NyGuard IGR?
    A

    PT 221L Residual Aerosol is labeled to control cockroaches so it would work if you want to use this as a residual spray. The best way to eradicate roaches in the home is to use a combination of a residual spray, roach bait and insect growth regulator. Sanitation is key to a successful roach treatment, the chemicals can only do so much so you need to be aggressive and consistent with treating.

    A better roach treatment program would be with one of our Roach Control Kits that provide enough product for the initial treatment and follow up treatments that are required every 10-14 days.

    Please take a moment to review our step by step Roach Treatment Guide for more information.
