I used Ambush last year and I’m using it this year. This is just my experience with it.
It is expensive, but quick. I dip the whole trap, chain and drag.
I have about 8 dozen No BS Extremes. Most have chain and drag, some have super stakes ground anchors. The traps come with a good coating from No BS. The coating wears off over time. I have traps from seven years old to new ones. I dipped them all, new and old.
I used to dye and wax the old traps that lost their factory coating each summer. I’d just wax the traps that still had the coating.
The Ambush lasted much better than wax alone. I set, pulled, moved and reset my traps for about 8-10 months. I do full time predator control on Central Texas. I don’t change traps when I have a catch. I reset it.
When I pull a trap, it may get reset on the same ranch or another ranch. Or I may take it home and lay it out on a cement slab next to my barn. I’ll wash these traps off with a hose spray nozzle or power washer. I’ll use these traps to set the next ranch. Set, reset, move, clean, move and set. Over and over.
I didn’t re-dip any traps last year. By the end of the 8-10 months, the Ambush was worn off in places. Some traps more than others. But I would have had to re-wax the traps multiple times in the past.
I saved many hours of re-waxing over the year. It was a big time saver for me. My plan this year it to just take my traps and dip them after I power wash them. One and done.
NOTE- I tried it on some snares. It worked on snares with non-mechanical locks. Like smoothie and mini pro locks. It gummed up the death blow cam locks. I had to throw the locks away after dipping them in Ambush. Just FYI.
