Selling home (NE) - I cannot move all of my pets during the showing. What are some other options?

Hello everyone. I hope you're enjoying your week.

We are planning on putting our home up for sale in the next couple of months. We have two cats and a dog who we will absolutely be able to have out of the house while the home is being shown.

However, we keep quite a few invertebrates. About 70. All of them are in tanks or some sort of enclosure (obviously). We just don't have anywhere to move them and keep them repeatedly for showings. Luckily they don't smell and are quiet (outside people have confirmed this) but a lot of their tanks are large and heavy and I just wouldn't have any way to move them quickly.

We have no friends or family in the area that we could store them at while we are selling the house, and I don't feel safe having them at our vet.

My thoughts were to simply cover them with a sheet while we are showing the house. Does anyone else who sold their house with a bunch of bugs in it have any other solutions that worked well for them?
