Turtle Nest Cages
Turtle nest cages help protect vulnerable eggs from predation - and help Ontario's turtle populations grow!
What are Nest Cages for?
Turtle nest cages help to protect the newly laid turtle eggs from predation. Turtles dig holes and lay their eggs underground but predators are still able to find these nests through their sense of smell. Turtle cages are designed to protect turtle eggs from predation when they are most vulnerable.
Why do Eggs Need Protecting?
Many common wildlife species such as raccoons, skunks and foxes can entirely destroy a turtle’s nest. Increase in the predator pressure, due to their ability to better adapt to city life compared to turtles, puts disproportionate pressure on our slow growing, low fecundity turtle species.
All of Ontario’s native turtle species are considered a Species at Risk. With their slow reproductive rate and high hatchling mortality rate, these species are very slow to recover from any loss to their population. Properly protecting nests and eggs from predation can greatly impact the species’ recovery rate.
Turtle Nest Cage Fabrication:
- Lightweight construction to easily carry to nesting site.
- Nest cage should be weighted down rather than held in place using stakes because nests are very dense. underground and you don’t want to disturb/ damage them.

Dos and Don’ts of Placing Your Nest Cage:
- Leave nest cage in place for 48 hrs at most. By this time, the smell of the newly laid eggs is mostly dissipated which is the main way predators can detect the eggs. Leaving the nest longer can lead to poaching or to accidently trapping the hatchlings inside if the cage is forgotten or the hatch time is mis-estimated. These cages are designed to keep predators out not keep turtles in.
- Make sure you don’t attract predators such as raccoons and skunks to the nest area.
- Respect the welfare of the animals and do not handle them.
- Avoid destroying or disturbing surrounding habitat.
- Watch, share and educate your family and friends on the incredible journey your nestlings are about to take.
- Report locations to the Adopt-a-Pond or Ontario Nature App if you see a turtle. For more information, click here.
