The first thing you need to do is decide if you really want to do it. You really can’t do trapping half way. And you can’ be doing it for the money. There is not enough money in it to be worth the effort. You have to love doing it. If you don’t you will not last the season and you will have wasted the money it cost to buy the equipment which can be a considerable amount of money.
The next thing is to decide what to trap. Once you decide you can buy books/dvds to help you learn the specific about trapping that particular species. In my opinion it is very important to learn all you can about it so you can make correct decisions when the times arrive.
Other than that are a few tips.
Trapping one or two species well is a lot smarter than trapping more species poorly. Trapping coon is a lot different than trapping beaver and they both require their own specific equipment and techniques. You are best off sticking with on or maybe two species and doing it right.
The cheapest traps are not always a good deal. I would never buys Duke traps for instance. The money you save on the traps you will lose on replacing springs and other parts.
Traps are expensive. Do not let people know where your line is. Try to not be seen working you sets. There are many people who do not like the idea that traps are in their area and will steal or sabotage them.
Again, traps are expensive learn how to boil and dye your traps correctly so they do not rust.
Buy warm, durable waders. Cabela’s Ice Busters have worked well for me. Cheap neoprene will not last a season.
All navigable waterways and road ditches are public property and can be trapped. If you trap ditch right of ways you will stand a good chance of upsetting people who live in the area. I can tell you from experience that even though this is legal it is generally not worth the headaches.
Land owners will be much more likely to let you trap their land if you are using leg hold sets rather than conibears or snares.
I hope this is enough to get you thinking to start trapping. Once you decide what species you want to go after feel free to PM me and I may be able to help you more.
