When the lakes rise High Water in the Lake Theresa Basin Pushes Rodents Uphill
Deltona’s lakes are linked in chains, and some of them drain slowly. After Hurricane Ian in 2022, the city got 11 to 15 inches of rain from the storm and about 20 inches for the month of September. The Lake Theresa basin, which includes Lake Theresa, Dupont, Three Island, Angela and Butler, flooded the worst. Some lakes and ponds were still over their banks 3 weeks later, and Hurricane Milton brought more high water in 2024.
Water that sits for days or weeks floods the burrows Norway rats (Rattus norvegicus) dig along banks, under sheds and beside slabs. Mice and rats living in the brush at the water’s edge also lose their cover. They do not go far. They move to the closest dry spot with food, which is often a garage, a shed full of stored items or the space behind a stacked woodpile next to the house.
That is why we see a jump in rodent calls on lakefront and low streets once the water starts to go down. Floodwater can also loosen soil at the slab edge and soak door sweeps, weather stripping and foam seals, so openings that were tight before the storm may not be now.
If water got into your garage or under your home, ask us to check the base of the walls and garage door seals, not just the attic.
