Just a thought...if the coon are coming for the corn, you'll never get a coon to work that trap if you only bait it with corn inside of it. You need something in it to truly give them a reason to put their hand in it and to work the trigger. The egg trap has an advantage of having super eye appeal due to its white coloring, but just like any of the other pet resistant coon trap models the coon needs some additional incentive to put its hand in the hole, so to speak. I've used the egg trap, Duffer's DP model, coon cuffs, and the little griz all with results. I prefer the coon cuffs but only because I like a push tigger vs. a pull-type trigger due to my set making of using the trap emedded into side of a creek bank or in a coon trail.
Was going to mention that unfortunately ALL of these models come with a price. You can build your own pet resistant coon sets using a simpler and less-costly foothold designed to hold coons. Make a small plywood box with a 2" opening and set the box right over the opening of the foothold bedded beneath the opening. Saw an article recently where someone made these out of a short section of large diameter PVC pipe and appropriately sized cap with a hole drilled in it.
Anyway, you could make several of these plus buy enough 1-1/2's or similar coon sized traps to go with them and have an entire arsenal of coon takers vs. just the one egg trap that you ordered, jsoukup.
Your one egg trap wil take coons, but if you have an issue with coons and need to get them cleaned up then you may want to consider "upping your odds" so to speak and invest similar dollars but end up with multiple traps to set vs. just the one you ordered.
For incentive to stick their paw in your hole, can't beat loud fish oil, or canned mackeral that has sat out for several days at room temperature. But if cats are an issue, you'll need something not as attractive to the feline predators...and a very loud fruity bait such as slightly fermented mellon or other fruit has worked for me well. So will a bottle of anise oil or other odorous oil scents such as mint, spearmint, cherry, vanilla, etc. In warmer weather peanut butter works good too but it really attracts mice and squirrells.
