Creepy Crawlies Trait

Does anyone else put this trait on home or community lots outside of Selvadorada to add a sense of realism and or danger to their game? My current sim was "shipwrecked" on the island in Windenberg so I gave the lot the trait as it felt realistic to the scenario. His mermaid wife got bitten and might die of poison. They are living off the grid at this stage in the game and are not allowed to go anywhere other than The Bluffs so she has no hope of an antidote. My guy might end up being a single dad soon but at least it's making the game more interesting!
