Ants eating the bait off mouse and rat traps

Ants are completely taking over and cleaning the peanut butter or bait off rodent traps before any target pests can find it. Spraying the surrounding area with bug spray fails to stop them, leaving traps useless and preventing homeowners from catching the mice and rats.

Both times I’ve put out the rat trap, the ants have completely taken over the bait, even after I sprayed the entire area around it throughly with bug spray.source ↗

every single mouse and rat trap being completely cleaned of the peanut butter, so I'm wondering if it's ants as I get ants on the front step.source ↗
