I have Drione dust, Delta dust D-fense dust and Tempo Dust. Each have their own mode or method regaurding IPM. HOWEVER when it comes to yellow jackets that infested the tiny crevace at the start of my aluminum gutter which butts to the siding and they nested down on the inside of the eve of the siding. NO possible way of any spray without serious backsplash and excessive runoff...Wait Until 9:30pm-10pm. The wasps will be totally dormant. Approach with a headlamp using ONLY RED light. Wasps do not have good vision at night and cannot see red light. They will gravitate to yellow light however...first thing I did was slip the CB80 straw inside the tiny section and held down on the applicator for 8-10 seconds...Nothing...the I got 2 bulb dusters the b and g and the puffy d. Both dusters do NOT disperse sufficient plumes vertically. So a ladder was also called into play. Both dusters were filled 1/3 up with tempo dust 0.1% cyflutherin. The B and G I placed 2, 3/4" washers inside to help agitate the dust when shaking it. Managed to send plumes of dust inside the hole and all around the surrounding areas. Proceeded to then take a screwdriver to open up the aluminum just a bit more when a white yellow jacket fell out at me, freaking me off the ladder in a hurry. Puffed more plumes in and around the hole. People, think of this more like a smoke than a dust. It is VERY fine, it travels like smoke and acts like smoke. Per my application a full face p100 respirator was employed. Managed to get just a wisp of dust on my bare arm and in 5mins it turned red and started to slightly burn. Stuff is POWERFUL. Make sure to use chemical resistant gloves, having pants and a full face respirator coupled with the gloves on a humid August night makes for a very uncomfortable and sweaty job, but PPE is paramount. Woke up today, and I have not seen a single yellow jacket come in or out of the hole. Repetition is key on an inaccessible nest. Dusted this 3 weeks ago prior to my vacation and the yellow jackets did not all die, and it grew to a massive proportion. REMOVAL of the nest is PARAMOUNT as well. The larva is extremely hardy (found out last year when I treating a ground nest. 1 gallon of Permethrin SFR at highest allotted rate mixed with scalding hot water...hot water significantly reduces permethrin efficiency keep in mind...found out after the fact, yet dug out 3 pancake size hives filled with transparent blue squirming larva and several soldiers were kicking.) The queen will overwinter with her brood and in a place so well protected, the nest will become all the bigger the next summer...so today I will remove the soffit and open the side of the gutter housing with a can of PT WASP freeze in my 1 hand and a bad mitten racquet in the other! TEMPO DUST is hand down the BEST dust for flying, stinging insects and areas that are not accessible due to how this product works..again think of it more like a smoke and less like corn starch. Stuff will torch your lungs if your not wearing the proper PPE. Protect skin, eyes, lungs when using this product or any product for that matter. (Side note, dusting at night is much worse as you think the dust dissipates and you go in for a closer look, all the while its raining down on you) just be safe, follow the label. This is professional stuff and alot safer than the organophosphates like chloridane or Dursban. Really amazing product!
