BASF Alpine WSG Water Soluble Granule Insecticide, Indoor Outdoor Pest Control for Ants, Flies, Bed Bugs, German Cockroach, 200 Grams

If you have a roach infestation, don’t wait, buy Alpine WSG now! I highly recommend getting more than one packet. Following the directions, I mixed 2 packets in a gallon pump sprayer I bought from Amazon and sprayed the entire perimeter of an Airbnb we’re renting. This is a non-repellent meaning that it will not encourage roaches to avoid the area. Instead they will carry on as usual, unknowingly walking over the insecticide, bring it back to their friends and family, and create a mass unaliving. The city here has a major roach issue we were not aware of so we were quite surprised to see so many roaming around our second night here. The following day after spraying, I saw one slow moving roach. The following day was the same. The next day, I saw one dying roach. And now none at all. We no longer see entire family reunions of roaches here and I’m glad I can help the host out, even for a little while. Saved them hundreds of dollars and gave me and my family peace of mind for the remainder of our stay. It dries on clear, lasts about 30-60 days, has a very faint smell when applying but that quickly goes away when it dries. Safe for most pets once dry. Just make sure to rotate products every once in awhile to prevent tolerance in future roach generations. It kills other bugs too which is a nice plus depending on your situation. Very easy to mix and apply.

When I moved into my trailer, I had been informed that the place had been previously treated by a professional for roaches... All I can say is that they didn't use Alpine WSG. It didn't matter what I did, you'd think I lived like a hoarder for how many were creeping around my clean, tidy little place. This stuff had me go from seeing several roaches of various sizes every single day in numerous rooms of the house, to one or two here and there (all acting strangely, after encountering the product), to nothing at all. I'd tried all kinds of stuff before I tried Alpine's granules, from baits, contact spray, diatomaceous earth, to growth inhibitors and nothing else really seemed to make a dent in my infestation. Half of a packet helped me treat about 800 square feet, just working along the baseboard and in all of the nooks and crannies I could reach. My neighbors are still dealing with roaches, but they never seem to make it inside of my place anymore since I made my perimeter around the outside of the trailer, along the windows and frames of the door. It seems extremely safe and left no weird residue or off putting smells to boot. For the price, effectiveness, and quality, this stuff can't be beat! If you don't mind mixing your own spray, it's well worth the effort.

If you've found this review because springtails have invaded your house and you've realized almost nothing kills them, I'm sorry. When I first moved into my place, I discovered it had a massive springtail problem (as in, I killed *hundreds* everywhere every single day). This area had apparently been a thickly wooded forest before they built the complex. They also insist on having flower beds with wood chips surrounding the outside of each building, as well as running the sprinklers every night, which creates a nice damp home for things to breed in (fyi, if this doesn't match your living situation at all, you may instead have a leak somewhere that's creating an ideal home for the springtails, so check for that). My complex's pest control was useless, no matter how many times they came out. I tried diatomaceous earth in crevices, but I think I would have needed to sprinkle it literally everywhere to kill them all, which wasn't an option. Enter Alpine WSG. I'm not going to say it's my favorite thing ever to do my own pest control, but using these granules is pretty easy. Just invest in a decent pesticide sprayer and pesticide-safe gloves, dress in long sleeves and pants, follow the mixing directions, and start spritzing. I usually treat at least a 2-3 foot perimeter around the outside of my house with liberal soaking of the piles of woodchips. I'll repeat this every few weeks about 3 or so times starting in spring, and they'll stop popping up inside completely afterward and will be rare to see outside for 4-6+ months. I have 20 lbs dogs, and this has been fine to use around them. Just wait a few hours before letting pets outside to make sure it all dries first. I also sometimes use the spray inside in select spots, and it appears to be very long-lasting. I've unfortunately found some roaches inside recently, despite being very clean (the complex says they're "wood roaches," but I'm dubious), but all of them were either dead or dying next to spots I'd previously sprayed. It had been a few months and multiple moppings since I last sprayed inside, so I decided to put down a fresh coat to nip the problem in the bud, and that seems to have done it. I haven't found anything inside but one dead centipede (did I mention it's not just springtails that live in the woodchips?) since. Fyi, I've found that Alpine doesn't kill most spiders, no matter the size (we have both tiny house spiders and very big ones -- wolf? grass? --here), so you will need something else for those. I also have had mixed results with the earwigs that wander in sometimes. They do eventually die, but I can't say for sure if that's the spray or their natural life cycle; they always seem pretty lively whenever I find them. As for ants, I have never had a problem with them because Alpine is incredibly effective against them. While the complex and my direct neighbor have sometimes had a big ant problem, when I've found groups of them by my place, they've already all curled up and died before they made it within two feet of my front door. This spray also does kill crickets, which is not my intention, but if you have a big problem with them, this would work. While I can't say if it's due to the Alpine, my dogs' own flea treatments, or just pure luck, I've also never had a flea problem in my yard or house.

Even though I had a very light infestation of German cockroaches, I must admit that I had strong reservations about this product as every product designed for roaches claims to kill them. However, this product quickly put to rest any doubts that I had as I have gone from a very light infestation down to zero roaches within a 3 1/2 week timeframe. Although not cheap, the product is highly effective if used accordingly per the instructions… and quite a bit cheaper than a professional exterminator. There is no noticeable smell that is detectable. After applying my first application, I applied weekly for several weeks in a row. It has now been day 11 of not seeing any roaches. I highly recommend this product if you are looking to exterminate German cockroaches, however; be aware that persistence in your application of this product is paramount, as is patience.

Our dirty ahhh neighbors gave us bedbugs. Used this, allowed to dry, then applied cimexa. Used the 30gram to 1 gallon dilution, the strongest allowed by the label. Worked great. Haven’t seen a bed bug in weeks. Dries quickly and easy to use

Actually works pretty well we'll purchase again

Expensive and from the states. I used this with a pressure spray all over the house. I can't say it was immediately effective to be honest. Used with diatomaceous earth as a pet friendly solution. Took at least 3 months.
