BioAdvanced Termite & Carpenter Bee Killer Plus Foam - Expanding Foam Termite Killer for Wood-Infesting Pests - 18 oz Can

The nozzle on this is very easy to use, it fits perfectly in a carpenter bee hole, foams nicely and has killed many bees so far. This was much easier to use than the standard spray can with a straw attachment. I just wish the price was lower. The kind I had before with a straw was $6 and this was $18 so it’s a significant price difference for a different nozzle. That said the straw one I had stopped working after the first day and it was still 3/4 of the way full so at east this lasts longer.

It works! Period. I like the nozzle which is what the off the shelf brand from my local store lacked. I was treating Carpenter bees who had invaded my pergola, and needed something to insert the foam into the hole, not just spray it around. It cured the problem. A little pricey, BUT it is a large amount that should last me a couple of seasons. Very pleased. Did not try it on termites (we don't have formosas here that fly).

It's always hard to tell with termites, but this product seems effective. It's slightly tricky to use, but not worse than expanding foam, certainly. The nozzle looks adjustable, but it's probably better to leave it as it is. That said, this would be better either with a pointier tip, for entrance into small cracks and holes, or a removable straw extension. This is one of those products where you'll probably have to shake it occasionally during use, but you won't want to shake it and splatter foam from the tip. I recommend having a small plastic bag handy to put over the end of the straw when you have to shake it, and I also recommend wearing a glove at least on the hand you'll be using to move the nozzle around. Or tape a stick to the nozzle so you don't have to touch it directly. This product foams up somewhat and will help to wet down tunnels, etc, but it's not enormously foaming, and the foam melts quickly. It did mildly stain the wood I used it on, if that matters to you. The can had enough to fairly heavily treat about twenty linear feet of intermittent termite tubes and holes.

Just what we were looking for

I used this product "off-label" for a very large and active nest of yellow-jackets that was living under the foundation to my cement-slab portico outside the front door to my house. There was a half inch wide by 4 inch tall gap that the yellow-jackets were using as an entrance to their hive. I figured that if this product is effective on carpenter bees, it would be reasonable to expect that it would work on the yellow-jackets as well. Be forewarned that this product does not act instantly. I was aware of this and took appropriate precautions. Spraying took place in the early morning, maybe an hour before sunrise, before I headed off to work to ensure that the yellow-jackets were in their nest for the night. I cut the tip off the plastic tube so that I could insert it as far as possible into the entrance to the nest. I sprayed until the foam started to come out of the nest at which point I waited until the next morning before using another application. This yielded approximately 5 applications from a single can. The foam seemed act as a barrier to prevent exit from the hive, but does dissipate after several minutes. Yellow-jacket activity continued but diminished each day for about a week to 10 days after the first application after which there were literally hundreds of dead yellow yellow jackets on the ground outside the nest. I would strongly recommend this product based on my experience, but keep in mind that this does not kill the yellow-jackets instantly on contact.

Kills carpenter bees and larvae efficectively, and the foam seems to fill up the hole down to the end. I’ve seen larvae come out of the hole and die after treatment. But- While the cone shaped nozzle is a good idea, it does not stop the foam from coming out onto your hand (which you need touching it to hold the cone in place due to the flexible hose), and the foam sometimes sprays out the back end of the hose onto your other hand. Note: the foam is just insecticide, it does not do anything to permanently fill the carpenter bee hole. Somebody should make that though.

Worked great. Drill small holes and filled my wall with foam. No more bee’s without major drywall or siding removal

I use this to inject the insecticide foam into the carpenter bee tunnels. The product does indeed expand quite a lot, although another reviewer said it didn't, though maybe their holes were shallow or "false starts" that the bee abandoned. It does kill the bees. My main gripe is that the applicator is a flexible, rather droopy, soft plastic tube. That flexibility might be perfect for some applications, but certainly not for carpenter bees when you're up on a ladder filling holes in the fascia trim. I've docked them a couple of stars for that. As a kludge, I've fashioned a splint from a chop-stick and some rubber bands, which is an improvement over the droopy applicator but it would be great if they made this product available with a rigid applicator tube, like the one on the foam insulation for windows that is sold in cans.

I tried ordering this item twice and on both occasions I needed to be given a refund due to what was described as a faulty article. Bit frustrating. So in honesty how can I rate an item I haven't even been able to buy?
