Over the past 25 years, Trap had at this point served under seven royal cabinet secretaries. He remained in the job until his retirement February 1884.
Trap's work resulted in a lot of travel activity, In 1840, he escorted Christian VIII and Caroline Amalie on their three months journey around the country. Under Frederick VII the excursions became more frequent. The king was interested in archeology and participated in a number of excavations. Trap was present at Frederiksborg Castle on 17 December 1850, when it was destroyed by fire. He was involved in the rescue of around 300 paintings and other historic artifacts. He was also involved in the efforts to rebuilding the castle. Trap was also present at Glücksborg Castle when the king died on 15 November 1863.

In 1856, Trap and printmaker A. Bull acquired Em. Bærentzen & Co. His publications included Danske Mindesmærker, Danmark fremstillet i Billeder and Danmark i Billeder for Land og Sø. In 1874, Trap became the sole owner of the publishing house. He ceded it to his son Frederik Trap who that same year merged it with Hoffensberg & Trap.
