Mice Under Flooring - Need input

[Brian Wilson]

So bottom line up front, I’ve placed traps. Caught 2 larger mice and 1 vol inside my property. This has been over the span of 2 months. Despite still feeling scratching anytime I kneel down on the floor. I haven’t caught anything in over a month. The tenants left a little over a week ago and they were dirty as can be.

The really weird thing is no matter what room I’m in they come and start scratching the floor any time I’m kneeling down or putting a lot of pressure in one spot. I have installed new lvp ontop of laminate and directly on sub floor. Both were clean. I pulled all the insulation in the basement (found droppings). Have had Orkin come out and do exclusion work this weekend. But not a single kill trap I bait has worked. 

I thought they might be in all the return air registers so I placed snap traps with dog food on them. Un-touched for over a week. 

I’m at my wits end here on how to get them out. I’ve put out poison balls. And bait stations. Nothing. Put out baking soda, flour and sugar mixture, nothing. 

I have not seen a mouse (other than those I’ve caught) or any droppings outside of the insulation I pulled.

Besides arson (joking) what you do at this point.

They are still there waiting you out.... . a) 3 5 gallon buckets with six inches of water and 3 of these https://www.amazon.com/PLANKY-...   walk the plank trap- it doesn't have to be that brand. Peanut butter on the plank and stairway to heaven. It catches live mice and they drown place. One in basement, kitchen, and near trash cans.

b) What are they eating now? Stored junk they stole from the trash? Is trash open? Seal it like Fort Knox and check for water leaks. 

Poison is gross because they stink minimum 30 days and can poison other animals.
