Tri-Die - 8 oz.

Whitmire Tri-Die Aerosol combines the repellency of pyrethrin and the long term stability and repellency of silica dust. Tri-Die leaves a dust residual behind after spraying that kills a wide variety of insect pests. Tri-Die is great for wall void applications and crack and crevice treatments.


Active Ingredient: 8% silica gel powder and 0.6% synergized Pyrethrin
NOT FOR SALE TO: CT, NY, NE, SC
Manufactured By: Whitmire Micro-Gen (Manufacturer Product Number: 59012764)



Prescription Treatment Tri- Die pressurized dust offers a convenient, easy application with no additional equipment necessary. Pressurized, charged particles penetrate deep into cracks, crevices, wall and ceiling voids to provide an ideal uniform dust application, readily adhering to all surfaces. The unique 4-way red application straw can be used for void space application to deliver 360-degree coverage. Tri-Die is manufactured with Whitmire MicroGen's innovative MicroPro technology. Tri-Die offers three way insect control - contact, repellency, and residual effect. When an insect crosses through an application area the dust is attracted to the insect's oily or waxy outer cuticle and the insect loses body moisture and dies. The naturally derived active ingredient in Tri-Die creates an unsuitable environment for insect pests. Tri-Die is available in a convenient 8 ounce can making it easier to use in confined spaces and easier to store.

 

Treatment Recommendations:

Interior:

Inject dust into wall void areas around windows and door frames, openings around pipes and sinks, behind baseboards and beneath carpet, in cracks and crevices of cabinets and pantries, sewer and floor drains. In food areas: Apply to cracks & crevices and void areas between different elements of construction, between equipment and floors, openings leading to voids and hollow spaces in walls, equipment legs and bases.

Exterior:

Apply dust behind siding, into wall voids, around window and door frames, into cracks of foundations and other places pest may be entering the building. For Carpenter Bees, apply directly into entrance holes.

    5 of 5 Stars  Long lasting residual
    By Jenny on July 19, 2008

    I worked with a reputable pest control company for 8 years and I have found Tri-Die to be a great repellent. I used this product for many insects. The beauty of this product is it is a long lasting residual and will keep most pests that come in from outside through cracks and crevices out of your home. It does leave a powder film where it is applied, so make sure you use only in wall voids and cracks as the label states. My target pest presently is ants.

    5 of 5 Stars  Tri-Die Kills
    By Ron on May 1, 2010

    If you have carpenter bees, this stuff will take them out. Using the included tube, I sprayed this stuff in the hole and moved to the next hole. By the time I got to the third hole bees were falling out the previous two and dying. Wait a few days, then plug the hole with wood putty or cork. Done. The can says it works on other pests, too. I have to believe them, given it's effectiveness. I ALWAYS wear protective gear -- gloves, safety glasses and some kind of mask.

    5 of 5 Stars  Kills carpenter bees!!!
    By Ben on May 26, 2010

    In all the holes I could get to this seemed to work great to get rid of my carpenter bees. It leaves a white residue so be careful on trying to just spray where you need it to unless you want to have a big clean up issue afterwards.

    5 of 5 Stars  Problem solved!
    By Jo on August 31, 2008

    Tri-die has rescued me on numerous occasions- particularly from ants. This weekend I've discovered it's a sure fire way to battle Springtails coming in around a window and french door. The Springtails have been freaking me out because two other professional insecticides that I normally use to handle just about every desert-dwelling insect that attacks my home had failed. This morning I remembered the can of Tri-Die and put it to work. Problem solved. Unfortunately my local Bug and Weed Mart has stopped carrying it. I'm happy to learn that I can order it online!

    1 of 5 Stars  Not Sure It Works For Carpenter Bees
    By Stephen on May 26, 2012

    Although Tri-Die was offered as a solution for carpenter bees, there was nothing about them on the container itself. I tried it anyway. Injected a one second or so shot into the hole and cleared away the collected sawdust. More appeared the next day indicating that the bee(s) were still alive and kicking. Tried again with maybe a 4 or 5 second shot. No new sawdust for 3 days. But it is back again. Will try one more longer shot. If that doesn't work, I'll have to conclude that Tri-Die doesn't work for carpenter bees. Had to give it a minimum of one star. However, no result merits no stars.

    Don't know yet, because there was only one sighting of an ant, and since spraying none, but that is not proof. We'll see, but so far so good (after 2 weeks)

    Verified Purchase

    This stuff works great. I love the smell it leaves, like a peppery smell, but It does great at killing ants and keeping them from returning to a treated area. I also love how the little spray stem is punctured so that it shoots all over the place once you get it in a wall void. Awesome job and I hope that this stuff is available for years to come...

    I had a carpenter bee reinfestation that was going on maybe four years of them being in the spot I finally tried this product and I'm ecstatic this stuff really works the spot was about 24 feet high on it go two story home so its hard for me to get to it I rigged way to get up there to their infestation and spray the area they were starting to die before I could climb back down the ladder that's been about 3 weeks now since I use this product and I'm not seen a carpenter bee sense now I can get back up there and plug the insulation holes. I will always come back to this website if I ever need any more type of pest control items because this saved me about 2 to 3 hundred bucks or more.thanks you Joe

  • 4 of 5 Stars  Seems to do well, but did seem to block the spray straw.
    By Julian on February 8, 2012

    I used this to get rid of silverfish in awkward places. The silverfish problem went after a spray, but i will say, the nozzle and spray was a little finicky. Could have been just my can though. As far as getting rid of the bugs, it deserved a 5 star. I'm only knocking off a star, cos my can was a little finicky.

March 9, 2011Daniel asked:

QI've have used Tri-Die, which works very well, but the darn thing jams.

A

Tri-Die is also subject to clogging, unfortunately that is just the nature of aerosol dusts. If you follow the tip below, you can help prevent any aerosol dust from clogging:

Tip: To prevent aerosol dust from clogging, make sure to turn the can upside down after each period of use and spray until just air leaves the canister.  This will clear the nozzle and keep it from oozing, and prevent clogging.

QCan I use "Tri Die" to treat for Wood Carpenter Bees?
I know Delta Dust is the thing to use then plug hole, but I had someone come and treat my porch and they used a wet spray that dried to a powder that was called "Tri-Die". I read the label on the can for what it kills and it never listed carpenter bees (or any bees for that matter).... Although they were dropping left and right... Is it safe to say that "Tri-Die" will also work in killing these carpenter bees?

ATri-Die contains the active ingredients Pyrethrins and Silica Gel. This combination of active ingredients offers a pretty fast knockdown and residual control of lots of insects, even those the product is not labeled for.

QCan you use Tri-Die for bedbugs?
If I understand correctly, you can spray Tri Die on the fold and tufts on your mattress and box spring to instantly kill bedbugs. It has the residual effect of silica gel or DE for future killing. Is this correct?

A

Tri-Die does contain pyrethrins which offers a fast knockdown of insects when they are sprayed directly, and also contains silica gel for residual control.

According to the product label, "Take bed apart and treat cracks, joints and interior of framework. Mattresses and box springs should be treated especially tufts, folds, and edges. Picture frames, moldings and all cracks and crevices in the room should also be treated."

April 10, 2011Brian asked:

QWhat area can a can of Tri-Die cover?
How much coverage will one can of Tri-Die provide? For example, if you were to inject the product into holes along a floor into a wall (as I am doing), how much wall could one realistically do? 10 feet, 100 feet?

A

There is not a coverage area on the product label, because it really all depends on how and what you are treating, and the person that is applying the product is a factor as well.  You do not need a lot of dust per hole or application.  The product comes with a straw that has holes in it so it literally shoots the dust in all directions in a void.  The product label states: Use Tri-Die with the supplied actuator and injection
tubes. Inject Tri-Die into cracks and crevices or void spaces where insects may be harboring, living and
breeding. Place injector tip into cracks, crevices, holes and other small openings. Release approximately one second of product. Move injector tip along cracks while treating at the rate of three linear feet per second. For closed voids calculate the void’s cubic area and treat at the rate of three to five seconds per three cubic feet. For closed void areas drill small access holes. Several holes may be required in long-running voids. This product can leave a white residue. This residue can normally be removed with a damp cloth or sponge. 

Based on the verbiage on the product label of only releasing the product for 1 second per hole, we would imagine you could probably do close to 100 feet of wall space.  This is just an estimate.

QIs Tri-Die harmful to breathe in?

ATri-Die is a safe product to use but it is an aerosol dust product and it could cause irritation if it is inhaled. A dust mask should be worn to prevent dust inhalation. When applied according to the product label, directly into cracks, crevices and wall voids direct contact with the dust will be minimal.

QIs Tri-Die animal safe?
My problem is right outside my door in my two flower beds. I don't have flowers in there but there are wolf spiders, other spiders, centipedes, etc. I was wondering if I sprayed it, would it be harmful to my dogs (because they like to eat grass from there)? If it is harmful, how long should I wait to let my dogs out in that area?

ATri-Die is animal safe when used as directed on the product label. Tri-Die must only be used in cracks, crevices and voids. You should not spray Tri-Die out into the flowerbeds. Talstar P would be a better choice for this type of treatment. It is gentle on plants, safe to use around pets and people and labeled for a wide variety of insects including spiders. Spiders can be a bit tougher to kill than other insects because they do not groom themselves and ingest the product like other insects and take longer to receive a lethal dose of the insecticide. Having said that, using Talstar P would also kill the other insects that the spiders need for food, forcing the spiders to move to better hunting grounds or starve. We would also like to add that spiders and centipedes outdoors are largely beneficial as they kill other insects such as roaches, mosquitoes, gnats, wasps, ants ..... To stop them from moving indoors you can spray around your door frames, window frames, in a band about 3 feet up the foundation and out onto the ground in a 3-5 foot band around the base of your home.

QIs Tri-Die better than other dust formulas?
Is this Aerosol just as effective as the Powder? And do you still need a hand duster since it's in the aerosol form?

ATri- Die pressurized dust offers a convenient, easy application with no additional equipment necessary. Pressurized, charged particles penetrate deep into cracks, crevices, wall and ceiling voids to provide an ideal uniform dust application, readily adhering to all surfaces. The unique 4-way red application straw can be used for void space application to deliver 360-degree coverage. Both the Tri-Die and the other dust insecticides will do the same job in the end but the Tri-Die may be easier to apply to wall voids.

QMy can of Tri-Die aerosol is clogged. How do I fix it?
My new can of Tri-Die doesn't spray. I wonder if the nozzle is clogged, or there's some safety tab I didn't find. Any ideas?

ASometimes the nozzle can get clogged during transit or if the Tri-Die can was exposed to low or very high temperatures for some reason.  Try running the application straw and the nozzle under hot water.  Also, be sure to shake very well before using.  Please call us at 866-581-7378 if you continue to have any issues.

August 5, 2013Bob from Chalfont, Pa asked:

QIs Tri-Die effective against carpenter ants?

ATri Die will be effective against carpenter ants if you know exactly where the nest is and can spray it directly. If this is not possible, we recommend you use a product such as Phantom Aerosol or implementing a carpenter ant baiting program. These products will be transfered or carried back to the colony so that you will be eliminating the nest and not just the ants that contact treated areas.

QCan Tri-Die be used to kill carpet beetles?
Can Tri-Die be used to kill carpet beetles? The larvae are coming out from my baseboards and along the walls in carpeted areas. I would like a product that has a straw applicator that I can spray along my walls/baseboards.

ATri Die can be used to help eliminate a carpet beetle infestation. You should inject Tri Die into cracks
and crevices and/or voids where these insects may be harboring. When dealing with carpet beetles it is very important to find and remove the source of the beetles to get rid of them for good. To learn more about carpet beetle elimination please take a few minutes to read our article : Carpet Beetle Pest Control

March 5, 2010Dorothy asked:

QIs Tri-Die safe for a home that has pets?

AYes, as long as you follow the application instructions on the Tri-Die product label there is no danger to your pets.  Tri-Die is a dust that is meant to be applied in cracks and crevices and places that your pets should not be able to easily get too.  There fore there should be no issues between the product and your pets.
