Outdoor and indoor walls appear to be solid but many can be full of minute pest passages. Puny bugs can get through the smallest holes, so making your home completely bug-proof is difficult, even new homes with bug mesh at the base of the exterior walls still get ants. The larger gaps are the ones that need attention, you know the ones that mice, rats and bigger insects can get through. So, get on the ground, under decks and examine the house exterior with a flashlight and a mirror. Remember the golden rule: mice can get through a crack of 6 mm and rats through a space of 12mm. Take all the time needed to examine every square meter of your house. The crucial areas to examine consist of wall gaps, the foundation, doors and windows , dryer vents, exhaust fans, roof vents and gaps in the roofing materials.
