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.

Before I bought this, I would see a dozen bugs in my kitchen every morning, so I kept my kitchen clean and put away my cat's food at night but that didn't help, and they were starting to spread to the living room area in my apartment. I mixed and sprayed this insecticide on March 28th, 2026 under the fridge and the stove. The few bugs that do show up 3 days later are dying. I am going to use the other half of the packet soon to make sure they do not come back. I have been limited to spraying in places my cat cannot reach, but I think it works well. Update: April 7th, 2026 I am unable to find any bugs in my kitchen at any time of day. I will probably need to spray again, but I am happy with this product.

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.

I used this product when I was working in a pest control company and it's awesome on the inside of the home to control roaches. It works on ants as well. It's one of the best products I've ever used inside a.home

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.
