Typically, sellers are required to disclose known material defects about the property they are selling. This includes structural issues, plumbing or electrical problems, environmental hazards, and pest infestations. In fact, the Colorado residential disclosure form specifically requires the disclosure of "damage due to termites, other insects, birds, animals, or rodents."
If the sellers were aware of the mouse infestation and did not disclose it, they may have violated their disclosure obligations. The presence of mouse traps could potentially be used as evidence, but it's not definitive proof. You must prove the seller's had actual knowledge of the infestation.
We have handled cases dealing with mice infestations. Evidence such as indications of prior remediation efforts, expert witnesses, and any history of interactions with prior pest-removal companies, can all be used to prove your case.
