Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In May 2018, the Company commenced efforts to shift certain of the manufacturing and distribution operations of Oxitec's Brazilian subsidiary to a decentralized operation and as a result, the Company anticipates one-time charges of up to approximately $6,000 in the second quarter of 2018. These charges are comprised primarily of the costs to vacate its existing leased premises, the write-down of certain fixed assets previously used in production, and severance costs.
