Rat Control After Festivals and Weddings: Handling Food Waste

Festivals, weddings and big gatherings bring feasts, and feasts leave leftovers. Piles of food waste, open buffets, discarded plates and uncleaned kitchens can attract rats within hours, and the rats often stay long after the guests have gone.

This guide is for hosts, venue managers and neighbours.

The short answer

To prevent rats after festivals and weddings, plan waste handling before the event, use enough lidded bins, collect and remove food waste promptly and the same day, clean kitchens, serving and dining areas thoroughly, wash and dry bins, clear leftovers and packaging, avoid leaving food in the open overnight, and inspect afterwards for signs. For venues, build waste and pest control into the event process. Quick, thorough clean-up denies rats the free meal that brings them in.

Before the event

• Plan where and how waste will be collected, and by whom.
• Provide enough strong, lidded bins, and place them away from entrances and kitchens.
• Arrange removal of waste soon after the event.
• Check the venue for gaps, drains and signs of rats.

During the event

• Do not let bins overflow. Empty them as they fill.
• Keep food covered when not being served.
• Clear plates and leftovers promptly.
• Keep food waste out of drains.

After the event

1. Remove waste the same day: Do not leave bags or bins full overnight.
2. Clean the kitchen and cooking area: Wash vessels, floors, stoves and drains.
3. Wash dining and serving areas: Remove food residue from floors, tables and corners.
4. Clean and dry bins and the area around them.
5. Dispose of leftovers properly, and share edible leftovers promptly with those who can use them, in clean containers.
6. Remove packaging and decorations that hold food scraps.
7. Check drains and grease traps.

Check for rats afterwards

• Look for droppings, gnawing and runways in the following days.
• Place a few traps at likely routes.
• Look for burrows and activity near waste points.

For neighbours

If a nearby event leaves a mess, speak to the host or venue manager politely, and tighten your own waste and food storage until things settle.

For venues and caterers

• Include waste and pest control in event checklists.
• Have a regular pest control contract.
• Train staff on waste handling and reporting.

When to call a professional

If you see rats after an event, call a professional promptly, before they settle in and breed.
