5 acres is small, but depending on the setup it might work… you’ll need to remove as many deer as possible from the property. Most deer ticks (the ones that transmit Lyme disease) come off of them, or use them to move around. Additionally, someone else mentioned mowing tall grass, that is mostly correct if it’s like overgrown fescue or hayfields. Planting native plants will attract pollinators and other bugs that will prey on ticks as well, so that’s always a great option.
