The worldwide intensification of human‐associated exchanges favours the multiplication of biological invasions. Among mammals, rodent species, including the house mouse M us musculus , are identified as major invaders with profound impacts on native biodiversity, human health and activities. Though contemporary rodent invasions are described on several islands, there are few data describing ongoing house mouse invasions in continental areas. We first outline the known picture of the distribution of the house mouse in A frica. We then describe the ongoing range expansion of the house mouse in S enegal, in order to update its distribution area, assess the location of the invasion front, describe the spatio‐temporal dynamics of the invasion at the country scale and evaluate its impact on native small mammal communities. We briefly review the worldwide status of the house mouse, with special focus on its situation in A frica. Focusing on S enegal, we then use historical records and a large body of spatio‐temporal indoor trapping data obtained from small mammal communities over the last 30 years to analyse the invasion dynamics of the subspecies at the scale of the country. The geographic range of the invasive house mouse is surprisingly poorly known in Africa. In S enegal, we document a large range expansion of the subspecies in human settlements over the whole country within the last 30 years. The invasion is still ongoing further east and south within the country, and has major consequences for small mammal communities and thus probably for risks associated with zoonotic diseases.
