In Florida, heavy rains and sudden floods are not just disruptive, they create the ideal conditions for pests to invade your home. Waterlogged soil, backed-up drains, and soaked building materials open the door to a range of infestations that can take hold quickly.
As a local provider, Florida Pest Control understands the unique pest pressures flooding can cause in our subtropical climate. Here’s what to watch for and how to keep your home protected with our residential pest control services.
Why Flooding Increases Pest Activity
Floodwaters force pests out of their natural habitats. Rodents are displaced from burrows, ants flee submerged nests, and insects like mosquitoes and cockroaches multiply in the warm, damp aftermath. In Florida, where standing water and humid conditions are already common, flooding amplifies these issues tenfold.
Pests Commonly Found After Flooding in Florida
- Mosquitoes: Standing water left behind becomes a breeding ground within days.
- Rats and mice: Strong swimmers that seek dry shelter in attics, garages, or wall voids.
- Fire ants: Form floating colonies and relocate rapidly to higher ground, including yards and homes.
- Cockroaches: Often emerge from storm drains and plumbing systems during floods.
- Termites: Water-damaged wood invites termite activity, compounding structural damage.
- Small flies: Like phorid flies and fungus gnats, thrive in wet organic matter and mold-prone areas.
Flood Prep and Recovery Tips for Florida Homes
Before the Flood
While floods can happen suddenly, some proactive steps can help reduce pest risk. Our technicians recommend checking that outdoor drains are clear and functional. Seal entry points around doors, crawlspaces, and utility lines. Move firewood, mulch, or storage items away from the home’s foundation. If flooding is forecast, secure trash bins and cover potential water collection areas like garden pots or children’s toys.
If your home is in a flood-prone zone, a preventative pest treatment or inspection may be worthwhile to identify high-risk areas and apply deterrents in advance.
After the Flood
Once water recedes, cleanup should focus on more than debris removal. Start by clearing out waterlogged materials that could attract pests. Remove wet cardboard, food waste, or soaked insulation, and ventilate the property as much as possible to speed up drying.
Inspect areas like under sinks, behind appliances, and around HVAC systems. These are hotspots for moisture and pest activity. Look for droppings, nests, or signs of gnawing, especially from rodents. Termite activity can be triggered by water-damaged wood, so watch for bubbling paint, mud tubes, or soft wood along baseboards.
To limit mosquito breeding, drain or tip out all standing water, flowerpots, birdbaths, and gutters included.
