1pack Adv'ion Cockroach Gel Bait, 30g Syringe with Applicator

I bought this expecting the real Advion gel, but what I received looks completely off.The gel is very dark brown, like overcooked caramel – nothing like the usual light brown color it’s supposed to be.The sticker label is poorly applied, crooked and wrinkled, which is not what you’d expect from a legit Syngenta product.Tried using it and the cockroaches just walked over it like it’s dessert topping. No reaction, no deaths.Looks like I got scammed. Be careful.
