The first thing to do is to find the openings through which the mice are entering and to take the necessary steps to close them. Remember that they can squeeze through spaces as small as 1/4 inch.

To detect an indoor mouse problem, we suggest using Maheu&Maheu Glue Traps . For suppression, however, conventional snap traps are preferable. It is better to use peanut butter than cheese as bait because peanut butter dries out less quickly and rodents love it. Pea butter can also be used if anyone is allergic to nuts. Both these methods allow the bodies of small rodents to be recuperated, thus avoiding future odor problems from putrefaction.

Contrary to popular belief, there is no product on the market that can dry a rodent’s body without odor.

Outdoor, we recommend using moisture resistant paraffin-covered rodenticide block. They are more resistant to humidity and remain attractive to rodents longer.

Multiple-catch traps such as Pro-Ketch can also be used either indoors or outdoors.


  • Locate and block off any entry points
  • Set snap traps indoors
  • Set multiple-catch traps outdoors
  • Set up bait stations with rodenticide outdoors


  • Plug or put screen over any opening wider than 0.64 cm (1/4 inch)

Description and development

Mice are easily distinguishable from small rats by their little eyes and little feet. They weigh between 30 and 45 g. Their body measures between 6 and 9 cm. Their tails are almost as long as their bodies or longer. Mice have big ears in proportion to the rest of their bodies. The color of their fur tends to be grayish.
Generally, mice give birth to a litter of 6 to 8 young. They can have up to eight litters in a lifetime. A mouse’s lifespan, in a natural environment, is usually less than one year.


A mouse’s five senses are highly developed. Because they are very curious by nature, they tend to leave a mess everywhere. They eat about fifteen or twenty times a day, munching on small quantities of food, which they find pretty much anywhere. Mice feed mostly at night and are mostly active at twilight. Activity during the day is a sign of a major infestation.

These rodents can run, jump, swim, and climb. They can live in buildings and are often found in the higher parts of structure, such as the attic. Outdoor, they dig small dens and wait for the opportunity to enter nearby dwellings.


Mice have a habit of exploring anything new in their environment. A good way to take advantage of that natural curiosity is to change the location of traps.
