Chiswick House Gardens will be closed on either 24th or 30th of May for precautionary tree spraying to combat the serious threat of Oak Processionary Moth in the park.  Tree spraying is dependent on weather conditions which is why two possible dates have been identified.  Please check before you plan your visit on

The Oak Processionary Moths emerge from their eggs in Oak trees during May.  They harm the health of the 0ak trees because the caterpillars feed on the leaves leaving them vulnerable to other pests and diseases.  Oak Processionary Moth also poses risk to human and animal health because the caterpillars have thousands of tiny hairs which contain a substance which can cause painful skin rashes, eye and throat problems.

Following Forestry Commission guidance, a bacterial agent which occurs naturally and widely in soil, will be sprayed on the Oaks in the gardens by specialist contractors.  It is necessary to close the gardens in line with current Health and Safety legislation, and environmental protection regulations.

Chiswick House and Gardens Trust apologises for any inconvenience caused due to the park closure. Latest closure information will be posted with as much notice as possible.
