We spend a bunch of time on how to kill mice and rats and what they are and where they hide. This is all important stuff, especially on a blog dedicated to pest control information, but one thing that I think should be said and the public may not be too aware of it, mice and rats are fire bugs. Pest control professionals know that they are, I've seen this countless times in attics and basements where the insulation around wires have been gnawed on or crewed through all together, and this is why it is so important to keep mice and rats out and trap them if they are inside. If you have a pest control company, make it the first thing you say during a rodent inspection. Inform the client and recommend they get a good electrician in to repair or replace the wires that have been gnawed on. An ounce of prevention can go a long long way.
