Would you guys recommend to pick up some flake antifreeze? Throw some on the top of the dirt and under where you'd bed your trap?
yes, my experience is anti freeze will help you alot but it is super corrosive if your equipment isnt waxed.
you can sometimes get away with using the dirt right from the set/trap bed even if its a touch wet if you make the set from scratch with some antifreeze. that'll take initial night time freezes and is about all i do in the fall normally. as a step up using dry dirt/peat moss right from the start will be even better and take more cold but you'll probably still find yourself using antifreeze as the dry dirt will suck up some ground moisture and it seems that a rain is inevitable earlier in season. i tend to use dry dirt in the fall if the ground is saturated or we are getting persistent rain. that buys me a few days some times. but the wetter the conditions and cooler temps after you set, the more antifreeze you will need and the more often you will need to re-apply so you end up messing around with the set more often than i like.
when it turns super cold and the saturated ground freezes solid setting with dry dirt and some antifreeze will work out fine if it doesnt thaw or rain much. however, weather fluctuation is what causes the most havoc. a good solid day of rain turns most dry material i've tried into a wet mess and if your temps drastically drop it seem no amount of antifreeze will keep it from turning into ice block. not many days ago it was in 50's here. ground was already saturated. then it rained. night time temps now heading to teens, then single digits and then below zero. some of day time temps arent going to get out of teens. i find waxed dirt is about all that gives you a chance then. id use it more in the wet fall but if i do never fails that i;m out come this time of year. and wax dirt isnt fool proof. if the ground below and around is frozen solid and the weather warms with big rain it sometimes will pool in the waxed dirt bed as it can't drain thru ice and youll still end up frozen in place if temp quickly swings back to cold side
