While the house mouse is considered a commensal rodent along with the norway and roof rat other species have adapted to living with humans to the point where perhaps they should be considered commensal.
Our choice in landscaping plants, bird feeders and other factors provide optimal environments for these pests.
The gestation period varies among species with the house mouse being 20 days, white footed mouse 23 days and deer mouse 27 days.
Litter size average is six to eight with 6 to 10 litters per breeding life of the female.
Entry into homes is gained at low, mid and high level with the highest amount of entry in most cases at low (ground level). Mice however are excellent climbers and have no issues climbing brick, siding corners and other areas of home to exploit gaps of a 1/4 inch to gain access to the interior of home.
A very high percentage of homes nationwide (some researchers estimate 95% of homes) have mice nesting in attics. An attic is a great location for mice, no predators, insulation for nesting material combined with their ability to utilize food to obtain water needs metabolically from the food they eat all make your attic attractive to them. Acorns and other seeds are found stored in attic and other voids of home.
Noise levels can be extreme with clients often thinking noise is due to larger wildlife. Mice chewing on a wall stud or drywall especially at night does sound like a much larger animal due to quietness of home and resonating in wall voids.
Control is best achieved with a combination of both professional rodent baiting and or trapping and exclusion to limit mice entering home. Discreet Extermination can apply high quality rodenticides as well as repairs referred to as exclusion to limit numbers of mice entering home. The combination of exclusion and removal/baiting programs breaks numbers and ends the repeating breeding cycle through lower numbers of mice present.
No home or structure can be made 100% mouse proof as garage doors being open, mice traveling in engine and other compartments of vehicles and other factors could allow small numbers to enter.
Addressing common primary entry points is highly successful and combining with removal/baiting programs greatly reduces or brings situations to an end.
