FROM A SEVERE RAT PROBLEM TO A CLEAN, RAT-FREE PROPERTY!🚨
What started as a long-term rat problem, with rodent activity almost every night, ended with the source identified, a redundant drain capped, and a contaminated loft fully cleared and treated.
We were called out to a property in Durham where the new owners inherited a severe rat infestation. After five months experiencing rodent activity almost daily they called us.
We implemented a targeted rodent control programme to eradicate the rats on site. We then carried out a detailed drainage survey to establish how they were gaining access to the property.
During the survey, we located a redundant drain line running beneath a previously built extension.
The redundant drain was capped, eliminating the rats’ access route. Following this work, all rat activity stopped completely.
After a full month with no further activity, we returned to carry out a complete loft clearance, removing the evidence left behind by the infestation and applying a biocide treatment to help address biological contamination.
The result? A clean, treated loft and a property with no further signs of rat activity!
At Patterdale Environmental, we don’t just treat the problem — we investigate the cause and work to prevent it from returning.
We specialise in persistent rodent problems, detailed drainage investigations and identifying those hidden access points that others may miss.
