For an integer ℓ at least 3, we prove that ifGis a graph containing no two vertex‐disjoint circuits of length at least ℓ, then there is a setXof at most vertices that intersects all circuits of length at least ℓ. Our result improves the bound due to Birmelé, Bondy, and Reed (The Erdős–Pósa property for long circuits, Combinatorica 27 (2007), 135–145) who conjecture that ℓ vertices always suffice.
