Plain Old Victor Mouse Traps ?

Congratulations buckskin! You're officially building a better mouse trap! My guess is is like everything else. Just junk. I like peanut butter on a mouse trap. If you just dob it on top they steal it. But if you cram it in the bait holder where they have to "dig" for it, it's bye bye Jerry.

I have to open mine up a bit. And the peanut butter works good. In areas where other animals can’t get at it I put out some mouse candy, green blocks work on mice but I need the yellow blocks for rats. 

Haven’t paid attention to that, have been using peanut butter for decades.

Bacon bits work wonders, sometimes...

I got overrun with mice here over the winter and up to a few weeks back 
Went through over 20 pounds of TOM CAT green mouse blocks 
Had a bucket setting on a chair out in shop , had left the cover off the 8 lb pail 
3 dead mice in bucket , lot of droppings , and about 3 pounds of blocks gone 
By house 8 pounds in 2 weeks , another 2 pounds out by trees where i seen some holes at base . 
 I took some 2 pound plastic coffee cans , drilled 2 holes in them with 3/4 hole saw , then ran 2 pole barn spikes up through bottom to place bait chunks on , put some pea gravel in bottom to weigh them down - have to preplace the 4 blocks about every 4 days 
  Bought some yellow Just One Bite blocks - some eaten but not as much as small  Tom Cat blocks  . I have 5 of the plastic cans now set around house , going to make up a bunch more to place in and around shop .
 Son had some outfit spray around house and yard for ticks and mosquitoes and they put out to bait stations but never cam back to service them as am sure bait was gone in a week .Just have to figure out what tool opens them  
 Have a bait station that holds 12 of the Tom Cat blocks and that gets emptied fast also .

On the Victor traps the liquid mouse bait works well , have got more with that inside house and garage than other bait .
 Have a couple of the see through mouse catching traps 6 x 12 or so galvanized metal box with hole on ends . Problem is live mice - to dispose of them drowning is only way to clear trap without mice running ever where when opened

They have to compensate for the little buckied incisors too.

I use butter for bait, the real stuff not margarine. Seems to work better for me than peanut butter. Have tom cat and various other blocks out in the buildings too. Anything to keep the population as low as possible! What I hate is when the stupid coons start eating the mouse poison. It does kill them, in time. Expensive way to be rid of them though. In the summertime the darn crickets eat any and all mouse bait! They absolutely love the light green tom cat blocks. Catch a mouse in a trap and they start eating them too. Nasty little buggers! 

I have had success using a raisin stuffed into the bait crevice, one raisin will often last to catch several mice.
