As an electrician I come across rodent issues quiet often, they do a lot of damage to cables etc. if left unattended.
I always recommend Richard at SWPC to my customers without hesitation and they are always amazed at the lengths he will go to, to prevent future infestations, for me that’s important as they just damage the new cables when come back. Sometimes just putting poison down isn’t enough and you need someone who’s willing to find and block the initial access

Keep up the good work Richard
