If you want to remove the pheromones from the trail rather than blocking the trail, it will work better to match the chemical properties of your treatment with the trail substance. It’s likely to be a mixture of aromatic molecules (such as pyrazines) that don’t actually get removed well by various aqueous cleaners (whether acidic, basic or neutral).
Instead, try the same kind of cleaner you might use if you were getting pinesap off your hands: “goo gone”, lighter fluid, paint thinner, olive oil, gasoline, a ceramide lotion like Cerave, etc.
Apply your cleaner with a clean cloth or cottonball or other applicator at least 3 times across the trail, using a fresh applicator each time (if you reuse a cloth, you risk spreading the pheromones rather than removing them) and ideally wiping off with a fresh blotter in between each application. Your cleaner probably does not need to “soak” on the surface, so it can be fairly fast to do.
