BASF 4316277914 WSG-200 Gram Tip and Pour Bottle Alpine WSG 200G, Clear

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.

I am a retired pest control technician with over 27 years in the industry. This product was my go to for German cockroaches, ants, and other insects. I did not use it for bedbugs, but if you’ve got a German cockroach issue this stuff is phenomenal, same thing with ants phenomenal, labeled for interior and exterior use. You cannot go wrong with this product when you apply it according to the label. It mixes with water and there is no smell or very little smell associated with this product. You can apply it right on the German cockroaches or after it dries, they don’t know it’s there and they crawl through it and it gets on them and after they groom that’s it lights out. Yes it is pricey. The only product that kills on contact is aerosol pesticides. This does not kill on contact, but they will die and rather quickly. BE SURE AND READ THE LABEL!

Apparently due to severe drought here in the Southeast, I acquired an undesirable, first time ever German cockroach issue. I never went a night not finding several of the cursed things in and around the sink starving for water, denigrating my spotless house! These things are devastating, doubling their population every 11 days and digging in like a hair on a biscuit. I exhausted every grocery store available product battling them, motels, foggers, sprays, with very little effect. I was just before calling an overpriced, questionably effective exterminator but really didn't want to start down that ongoing rabbit hole. Following a recommendation from Arrow Pest Service on YouTube (hilarious dude and his adorable cornbread daughter), I reluctantly tried this expensive product, combined with also recommended Tekko Pro insect growth regulator (birth control for bugs) as a last stand. I mixed it hot at 30% strength with a generous dose of the IGR in a good quality sprayer and went to town tearing up the kitchen, pulling the dishwasher, refrigerator and stove and emptying cabinets. I found a brood nest in the insulation blanket on top of the dishwasher, but ground zero was inside the service panel of the fridge just like Arrow said would be found. Disgusting vermin, made me angrier than I already was. I vacuumed up everything I found in the shop vac to be unceremoniously drowned later. I sprayed the living daylights out of every crack and crevice I could find, focusing up around the farmhouse sink and countertops, and covered the dishwasher blanket. It's been two weeks now, and the war is basically won. I occasionally see a mutated juvenile specimen but not a single adult. As advertised, this product remains toxic to them while the IGR keeps the juveniles from maturing so they can never reproduce and the infestation dies off completely. I am confident that process will come to pass. Semi-annual retreatment will now be standard practice with this product, as I never want to go through this again!

I started with a newer, small pest control company, 6yrs ago. Having never done it before, I had to learn everything. I’ve used a lot of chemicals, since I started in 2020. This one by far, is the ABSOLUTE BEST!!!! It kills everything and I’ll never use anything else!!!!!! EVER!!!!!!!!!

As described and pictured. Reasonable shipping with good packaging. Did not interact with seller as everything straightforward and simple. 10/10. Well pleased.

Excelent! It got rid of the cockroaches in my house.
