In this work we investigate the decay and production properties of the strange double-charm pentaquark Pccs++ with strangeness S=-1. Building upon our previous work predicting its JP=1/2- molecular configuration, we employ three-point QCD sum rules to calculate its strong decay widths and estimate its production branching ratio via Ξbc+ baryon decays. The total strong decay width to the ΞccK and Ωccπ final-state channels is determined as 85±19 MeV. Furthermore, using a rescattering mechanism, we analyze the Ξbc+→ Ds∗-Ξcc++→ D-Pccs++ process and estimate the production branching ratio to be Br(Ξbc+→ D-Pccs++)=(4.3-1.5+2.0)×10-6. The relatively narrow width and detectable branching ratio suggest the possibility searching for this pentaquark state in the future.
