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."
Yes, the silica gel in Tri-Die can kill ants. The silica gel left behind as a residual will cling to their exoskeletons and desiccate them.
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.
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.
Tri Die is safe for pet after it has setteled and dried, 1-2 hours. Please see our Bed Bug Treatment article for the best information about treating for this pest.
Unfortunately we cannot comment on work done by a pest control company. We can tell you that the product label instructions are law and the product label is available for you to review on our website. The product label does dictate that the product should be used in cracks, crevices, voids and small spot applications. If you feel like these product label instructions were violated we recommend you call your local health department right away.
We can also tell that the product label does not indicate that you must be out of your home for 2 days or nights when used as directed.

If the Tri Die was applied according to the instructions on the product label there should be no cause for concern. It would be extremely unlikely that the service person would be able to accumulate enough product on his clothes or shoes in an amount that would be harmful just from walking up to your house.
Any insecticides applied on outdoor surfaces will eventually be removed by breaking down in sunlight and/or washed away with rainfall. Tri-Die contains natural pyrethrin, which breaks down quickly in sunlight, and silica gel, a natural dessicant that would likely be washed away quickly. The PBO synergist in the product also breaks down quickly once applied. We are not sure why the product would need to be removed from where it was applied, but you can always use a hose to water the area to remove any residual product.
Yes, Tri-Die contains both silica gel and pyrethrins as active ingredients in a pressurized insecticide dust. This is an excellent insecticide for crack and crevice and void treatment for many common household insects. This product will not offer quick knockdown, but it lasts for months in undisturbed areas. In order to give you the best advice on your situation, we would need to know what specific pest you are treating. A variety of stored product pests such as grain moths are often found in kitchen areas, and the most important step to treating them would be locating and discarding the infested food items, followed by cleaning, sealing up harborage areas, and residual insecticides.
Yes, Tri-Die is labeled for roaches. However, if you are dealing with a roach infestation, you likely will need to use other products as well in order to completely eradicate them. Please take a look at our article on How To Get Rid Of Roaches for more information and tips.
