It's not just a lid, you need to seal every possible opening including tubing, drains, overflow teeth, etc. They can get through any hole large enough to get their beak through and their beak is pretty small. As mentioned, they don't live very long maybe two years depending on species. However, if the female lays eggs that's pretty much it for her.
Blue rings are available and they are pretty inexpensive but you would really want to have something like that in your home because it isn't something you can relax around, especially if you have kids in the house.
