Bayer 03780574 Premise Foam Termiticide, White 18_ounce

I live in Northern California, close to wooded areas, where flying termites are an inevitable part of life here. After living in my house for 9 years, I recently had to treat for termites for the 3rd time during my stint of home ownership. The first time I treated my house years ago I paid a professional termite company to come and treat. They spot treated the infested wall with either this Bayer product or Termidor foam. The second treatment was thankfully covered under the 3 year whole house warranty by the same company. After watching the professionals treat using termite foam in my house twice, I realized what they were doing was incredibly easy work and I could definitely handle it myself the next time signs of termites popped up.Sure enough, 3 years later and the termites were back in a new area of the house. To be honest the house should probably be tented at this point but we have a newborn child and are not going to go through that process right now. I had the same termite company come out to inspect and bid the job just to make sure I didn't miss a bigger problem and they assured me a spot treatment of the infested wall was all I needed and quoted me $1,500 for the job using the exact same Bayer Premise foam that anyone can buy here on Amazon.Applying this product is really easy. I was worried that it would be hard to figure out where to drill the holes for treatment but I had 2 visible "kick-out" holes in my wall that I used as starting points and then worked my up and down the wall from there drilling every 6-8". I had no issues with the foam "blowing out" at the can head. If you're not certain whether or not you're drilled into a termite galley, only dispense the foam for a very quick <1second amount to start. You'll be able to quickly tell if the foam is expanding into your wall stud or if it immediately is hitting resistance and coming back out the hole you drilled. Only continue dispensing foam into the wall once your certain your in a termite passage. Continue dispensing for about 10 second per hole or until you see the foam coming out of your next closest hole.It's been 2 months since I treated now and there has been no signs of the termites coming back. There is really nothing more satisfying than killing all the little buggers eating your house from the inside out!

Okay, here is a little backstory. in 2022 I had a swarm of flying termites in my kitchen and with some flea spray I had I thought I got them under control. Oh but NO! Enter late summer of 2023. They were back in force. I called Corky's Pest Control and they wanted $2500 to tent my place or about $1200 to foam the walls. Since I only saw these critters along about 12' of wall area, I thought to try this stuff. I drilled 1/8" holes every 16" near the bottom of the walls in question and systematically sprayed this foam in each hole with the provided tip. I didn't know how much to use, so I did about 10 seconds of spray per hole going back to the start and repeating till the can was gone. The next day, I still saw them and vacuumed accordingly. On day two, I was getting upset. Still had the critters all over the floor and behind the fridge (I got that wall too). I had to take a trip for a few days. When I got back, there were HUNDREDS of them all over my floor and all dead. I cleaned them up and in the next few days, I'd see one or two each morning, also dead. It's been a few months now and they are GONE. I decided to not cover the little holes until next season. Just to make sure, I'm going to put one more can in the walls before patching even though I probably don't need to. This stuff is amazing. Trust me, no spray will kill the colony. You have to use something like this to have them carry it to the queen and the colony. End of story. End of flying termites. End of critter anxiety.

Ok, although I only just used the stuff so can't say yet whether or not it's good I felt like I should address the "problems" people been having with the foam coming out of the top where the button is. This will only happen if 1-the hole isn't long and the tip is pushed up against the end of that hole so the foam backs out back up the tube and comes out where the button you're pushing is, if you watch the tube you can see it going backward. You can try pulling the tip back a little, if it's a hole that leads to other pathways it will resume going in, if it's just coming out at the hole OR you get spitback when you pull it out, it's because it was a hole that went nowhere. If it does this just stop pressing the button down a wait a few seconds and slowly remove the tip from the hole and try another, you can also try drilling a bit more into the hole and try again. 2-Just press the button with a short quick press so that you're feeding the foam in slowly, unless it's taking it and not spitting back then you can hold that button down and it will fill that hole plus its branch tunnels or a large cavity, look to see if it's coming out at another point of the wood and stop if a lot of it's coming out, you've filled that hole and cavity move onto another hole. If it's a deep hole and the long tip will go in far enough use that tip, if not and you use a drill to open it up a bit the cone shaped tip might be better but the rules are the same as far as filling goes. You'll save a lot of the foam doing it this way with little or no spitback. Wear protective goggles and rubber gloves and long sleeve shirt, if you do get spit back this will protect you. I have every reason to believe this stuff will work, years ago it wasn't in foam form it was liquid with a hollow needle and a cone shaped suction cup to prevent same spit back and it was great stuff cause it filled the hole and you could see it start weeping out of the wood beams or posts showing just how bad a problem you had. I like that this new foam version will be carted back on the bodies of the termites it comes in contact with to the nest and the queen and other termites killing all of them. The best part is the money you will save doing it yourself and you'll learn where your problem areas are-moist wood so you can take care of that. If you notice signs they're still there reapply, if needed call pest control company, but when I used the old stuff it got rid of them and they never came back to those areas, I should've kept a eye out and eliminated problem areas, now I'm having to do a lot of wood removal and replacement outside the home, after inspecting under the deck there's holes but no termite droppings, even so I'm foaming all of them just in case, the wood's still solid-can't push into it with small screwdriver and sounds solid if tapped with hammer. Hope this helps and I'll do a follow up on how effective this stuff is but with all the great reviews I'm not worried just busy, but it's a good feeling if it's not a huge problem, you feel in control without having to call pest control.
