The Problem
A homeowner in Consett DH8 contacted us after noticing a large number of wasps entering and exiting the rotten back door frame of their property. The constant activity made it unsafe for the family to use the back of the house, particularly worrying with young children around.

Wasp nests in door frames are a fairly common issue, especially in older properties where timber has decayed. The soft, rotten wood provides an ideal sheltered cavity for wasps to establish their nest during the summer months. Left untreated, the nest would continue to grow and become more aggressive as the season progressed.

Our Inspection
On arrival, we carried out a full inspection of the property to confirm the location and size of the nest. The wasps were actively using a gap in the rotted timber of the frame as their entry point. We established that the nest was well established inside the structure but had not yet spread into the internal living space.

We also assessed the surrounding area for any additional nests or contributing factors but confirmed this was an isolated issue contained to the rear door.

Our Solution
We applied a professional-grade wasp control treatment directly into the entrance of the nest. This was carefully carried out to ensure both safety and effectiveness, with the treatment spreading through the cavity to reach the queen and the rest of the colony.

The customer was advised to avoid the back door for a few hours after treatment to allow the insecticide to work fully. We also discussed longer-term solutions, including the need for replacing the rotting door frame to prevent future infestations.

The Outcome
Within 24 hours, the wasp activity had completely ceased, and the area was safe to use again. The homeowner was relieved that the problem had been dealt with quickly and professionally, removing the risk to their family.

They also arranged to have the back door frame replaced, ensuring the cavity could not be used by wasps or other pests in the future.

Key Takeaway
This case shows how even small structural defects, such as rotten wood, can create opportunities for pests to establish themselves. By carrying out a safe, targeted treatment and advising on preventative repairs, we provided a complete solution — protecting both the property and the people living in it.
