He has made regularly appearances for the national squad since late 2004. In 2004/2005 he helped the Congo qualify for the 2006 African Nations Cup. Biscotte played in every match in the 2006 African Nations Cup where the Congo made it to the quarter-finals.
Perhaps his most famous moment was against South Africa in 2004 for 2006 World Cup/African Nations Cup qualifying. In the 87th minute he made a mazy run around numerous defenders deep in South Africa's end that set up Kabamba Musasa for a tap in goal that gave the DR Congo a 1–0 victory.Because of that victory the fan named him Pied de Jesus (Jesus' foot) and also named him sauvons le Congo meaning Saves Congo due to the fact that his intervention revived DR Congo's qualification chances.
Biscotte also featured prominently in the BBC documentary Frontline Football, part one of which followed the Congolese national team as they prepared for the match against South Africa. The goal he set up for Kabamba Musasa features as a perfect climax to the documentary.
