Bayer Tempo 1% Dust For Insects (1.25 lbs)

I noticed that bees were going through a crack in the mortar between the bricks on the front of my garage. I caulked the hole and a couple hours later the bees had chewed through the caulk and were back to business as usual. I next plugged the hole with mortar, and they chewed through the mortar before it could set up. I refilled the crack with mortar and covered the area with a board to give the mortar a chance to set up which it did. To my amazement, the bees found two other areas to enter the same nest. I went to a local store and bought two cans of a leading brand of hornet/wasp/bee spray and used it to saturate the two new entrances to the nest. The spray killed the bees it touched but after an hour or, so it was if I had not sprayed at all. The bees were back like nothing happened. I was talking to my brother about this, and he recommended two products that he used so I researched them and ended up buying Tempo Powder based on the reviews which were very encouraging. I used a bulb duster to spray Tempo Powder into each of the two areas the bees were using to enter behind the brick. It was obvious that they did not like the powder, but I worried about its effectiveness because I was not seeing bees falling to the ground dead as if I was using a spray. After making sure I had thoroughly sprayed both entrances I left the area because the bee activity was increasing. I came back to the area later in the day and was happy to see no bee activity at all. I checked for activity over the next few days and found none. It’s now about a month later and still no bee activity. I am very happy with this product. For my application, it exceeded my expectations and solved the problem. I have found that the leading brand sprays will kill bees on contact, but they will not stop the activity when you cannot spray the nest itself. Tempo Powder is my go-to product now for hidden bee hives. Just thoroughly dust the entrances and let the powder work its magic. The Tempo Power seems kind of pricey, but I am glad I took a chance on it based on the reviews and can only say that after seeing how it worked for me, it was well worth the initial cost and based on the amount I used in my first application, the 1.25 pounds you get should last you a long time. When I think about the cost and amount used for one application, Tempo Power is probably just as cost effective as buying several cans of normal spray at the store.

Worked great. We had a yellowjacket nest in a wall void, and I treated the area they were coming in and out of. Within 48 hours, we haven’t seen a single one. A great addition to the pest control arsenal.

I was worried that this wouldn't work in a wall cavity with fiberglass insulation. True to the other reviews, this product took care of the yellow jackets in the wall even with insulation. I drilled a few holes where I could hear them buzzing just large enough for the tip of my duster about 12" apart in a grid. I filled the holes in with spackling immediately after dusting. The nest was probably large, but after about 48 hours there was no activity.

I've used Tempo for years, mostly for ground wasps, but it kills any insect. I've also loaned my Tempo to friends who've had good success. It works very well, but it is not a 'knockdown' insecticide. It takes a day or so to kill the wasps, and for the wasps to move the powder around inside the nest. HOW TO USE THIS FOR GROUND WASPS (E.G., YELLOWJACKETS): [They aren't 'BEES', folks! Bees are beneficial and do not attack you unprovoked.] Carefully note the location of the hole during the day. Return after dark. Put on long sleeves and gloves, go out with a flashlight, and find the hole. Shake the Tempo container a bit (if it gets moist, it may cake), then squirt about a 0.5 - 1 teaspoon of dust into the hole, and around the immediate opening -- on the soil where wasps tend to crawl as they are entering/exiting. It doesn't take much dust, but YMMV. Wait a day and then observe the nest from a safe distance. You may need to repeat your treatment for larger colonies. A jug of this dust lasts for years and treats many nests. I have treated dozens of ground nests this way, and have never been stung nor attacked at night. Every year I find about a dozen nests on my property, which has prairie, rock walls, etc. The wasps seem to prefer drier soils in sunny locations. But last year I used Tempo to treat a colony that had six openings within a 7 foot area, under shade with rich moist soil. It's best to approach slowly and to study a nest area from a safe distance, watching where the wasps are entering/exiting. But caution: especially in August or late summer, the wasps may attack you just from walking nearby. I learned about this product from the invoice a professional pest control service left after treating a wasp colony living in the outside walls of my home. He used a duster, and, working during the day, while wearing all the beekeeper protective regalia. It worked well for him, and it does the DIY job just as well.

Does what it supposed to well, kills bugs quick knock down. Bottle opened in box during shipping, reason for the 4 star. When opening box was welcomed with a quick dusting of insecticide, at least the majority of the product remained in the bottle.
