Context: Debris discs orbiting young stars are key to understand dustevolution and the planetary formation process. We take advantage of a recentmembership analysis of the 30 Myr nearby open cluster IC 4665 based on the Gaiaand DANCe surveys to revisit the disc population of this cluster.  Aims: We aim to study the disc population of IC 4665 using Spitzer (MIPS andIRAC) and WISE photometry.  Methods: We use several colour-colour diagrams with empirical photosphericsequences to detect the sources with an infrared excess. Independently, we alsofit the spectral energy distribution (SED) of our debris disc candidates withthe Virtual Observatory SED analyser (VOSA) which is capable of automaticallydetecting infrared excesses and provides effective temperature estimates.  Results: We find six candidates debris disc host-stars (five with MIPS andone with WISE) and two of them are new candidates. We estimate a disc fractionof 24$\pm$10\% for the B-A stars, where our sample is expected to be complete.This is similar to what has been reported in other clusters of similar ages(Upper Centaurus Lupus, Lower Centaurus Crux, the $\beta$ Pictoris movinggroup, and the Pleiades). For solar type stars we find a disk fraction of9$\pm$9%, lower than that observed in regions with comparable ages.  Conclusions: Our candidates debris disc host-stars are excellent targets tobe studied with ALMA or the future James Webb Space Telescope (JWST).
