Question on the rodant problem is the wiring being chewed a lot less common in the heat of the summer then in the middle of the winter I would think that it would be a lot less in the heat of the summer varmints wouldn’t want to get up in a hot engine but in the winter they do want to nest in the warm engine compartment. just let me know what you guys think?
In general, mice and rats tend to move "inside" during the fall/winter to warmer areas. They are active all year, but the time to be especially vigilant for nesting and chewing is late fall/early winter. Other species such as chipmunks and squirrels use engine compartments and other cozy places in vehicles to store food in the fall and can chew on wires/hoses/plastics in the process. They don't usually nest there, though, like mice do. All species have a tendency for "repeat performances". Once an area in the vehicle has the smell of a nest or a food storage area, there is a strong likelihood of repeat use, even if the original offender is long gone. If you have an infestation, clean, clean, clean.
