Does it have a residual effect or must it have direct contact with carpenter bees?

From the applications I have made, it does have a lasting effect. However, it doesn't last forever. I spray about 6 week intervals.

This product will kill on contact, but it has to be direct contact. There is no lasting effect. So, you cannot pretreat an area. The bugs can and do return to an area that was previously treated.

I used it last summer (Tampa Bay area) and had good results. I put it in a pump sprayer and sprayed all around the doors, base of the house, on the walls, and deck. Not as many got in the house since they weren't hanging around the doors. With all our rains, I had to re spray every couple of days though. It seems to repel them for awhile. I didn't have as many getting in the house last season. If it looked like there was going to be a few days of no rain, I would spray the shrubbery too. You definitely need to strain the juice with some cheese cloth as you put it in the sprayer. It's garlic particles will clog the sprayer wand. I wore disposable gloves when handling the cheese cloth. That STRONG garlic smell will stick with you if you get it on you. It didn't get rid of them all, but it did help, and it's not toxic. Reapply as often as you like. Just don't spray the bees and butterflies directly.

According to this article from a scientific journal, they have minimal effect on the adult bees, and if the odd adult bee does get infected at a nectar source and bring it back to the hive, the infection does not readily spread to the brood in the hive. In other words, probably ok. But I'm not a beekeeper.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2619623/ (full article is available for free as PDF)

Don't know about the eggs. I assume it kills the larva on contact since it stopped the bugs dead in their tracks but it also doesn't have any residual effect either. A few hours after spraying it on pillows and my couch I found bugs crawling on the areas I had sprayed. I was disappointed. Since my epidemic was pretty much isolated to my couch and somewhat to my bed (soon as I discovered them I quit sleeping in my bed so they didn't multiply there). I eventually ended up hauling all my furniture out to the curb (it was old), put encasement's on my mattress and box spring and then moved 1,200 miles away. I haven't seen a bug since moving thank God. Good luck.

Treat their nests directly with Drione to insure long term control. Use Suspend SC, Cyper WP or Tempo WP on decks, overhangs and fence posts in the Spring to stop further nests from starting. A little prevention will go a long way in reducing the amount of unsightly damage caused by carpenter bees.

I used it for carpenter bees and ants and it worked well. I would try to use it because it has both an insecticide and silicon to act as a dessicant. Easy to use. get the duster and only get the smaller container. It goes far. I bought the gallon size and only needed a small amount to do the whole job (sprayed all my eves and soffit boards. Jim

I don't see how Honey bees could be affected. The Nemotodes only attack the borers inside the tree.

I bought it for yellow jackets and I can tell you it did NOT work at all. I was using the store bought peel and stick cardboard strips and they were working perfectly, although getting very pricey. I applied to this stuff to both the entrance and surrounding area as well as making my own sticky cardboard traps and hanging it up. This stuff did not work. Caught a lot of ants and really tiny mites, but that was it. I image the most it would do to carpenter bees is minorly annoy them.

I truly don't think so. How does one prevent bees from touching pesticides ? If it's raw, it's raw, I have had both and no difference in taste. I think it is marketing.

I would say yes it'll leave a chalky white residue that wipes off pretty easily withy a damp cloth. To minimize the residue I spray very lightly in places that show and pretty heavy in areas that either don't show or that don't matter. This is a very effective product, we used a pest control company for years just over a year ago we started using Demon it's better and cheaper than the pest control people. I don't spray inside anymore unless we see bugs, but I spray heavily outside to keep a protective barrier and keep the critters outside. My problem was carpenter ants and spiders this does a great job it's fast, easy and cheap. I would say yes it'll leave a chalky white residue that wipes off pretty easily withy a damp cloth.

From what I read on the manufacturer's site when I first purchased this is that it may harm them only if it is DIRECTLY sprayed on them. This is also why the recommend spraying early in the morning or late in the evening. When I spray, I actually walk backwards in hopes of disturbing anything in my path. I also use the end of the sprayer and shake it in bushes and plants to scare anything out, so as not to spray them directly. I use this about every two weeks on the perimeter of my yard and I honestly have fewer mosquito's and just as many bees and butterflies in my gardens/yard. I use specific plants to attract them as well. Hope this helps.

Hi KM., I wish I could help you, however I have no experience with carpenter bees.

The master gardener that I talked to said that it is effective on coddling moths and if you spray in the evening after the bees are asleep, it does not harm the bees.

I have used these traps for years and find them very successful for: 1. flies, 2. wasp, 3. other flying insects but no bumblebees. In fact I have one trap setting directly over our carpenter bees nest and none have ever gone in the trap. I personally use Hornet spray for the bees which kills immediately in hole or out.

I did not have a honeybee problem so I've no idea. I just know it did a great job at killing the fleas. Still no fleas and I applied it in September 2013 :)
