Have you ever noticed that more flies and ants linger when the ground is damp and the vegetation is healthy? Increased moisture around the foundation of your home, caused by poor drainage or high water tables, can lead to a pest problem. Mosquito Squad Plus in Schererville can help you understand how groundwater, heavy rain, and soil conditions can all influence how long dampness remains beside a home. The resulting damp zones may offer insects water, shelter, and access to structural gaps.
Does Schererville Have a High Water Table?
There isn't a simple way to generalize the water table for the entirety of Schererville. The level of the water table fluctuates with the seasons and is influenced by a variety of factors, including:
- Elevation
- Soil
- Drainage improvements
- Recent rainfall
Across Northwest Indiana, some properties may deal with shallow or high groundwater depending on these factors. Things like extended wet weather and poor surface drainage can lead to a higher amount of retained moisture. Saturated soil, water in low yard areas, sump pump activity, damp basement walls, or moisture along the foundation are signs you may be dealing with too much moisture. The local Schererville pest control page explains how professional pest service can address insects in moist areas around a property.
Why the Foundation and What Draws Ants
Ant activity follows the same routes as water for a few reasons. The main one is their need for water to survive, but also food and shelter tend to be more plentiful in moisture rich areas. Wet mulch, leaking hoses, and downspouts are usually up against the foundation of the home and are great shelter and foraging options for ants. Ants may also seek out small foundation cracks for convenient routes indoors.
Schererville sees carpenter, pavement, and odorous house ants among others. Carpenter ants seek shelter and nesting in damp and rotting wood, so increased moisture along the foundation or deck joist will draw in this species. Pavement ants commonly nest beneath slabs, sidewalks, and foundation edges. Explore the Mosquito Squad Plus pest hub for more information about pests found around homes and yards.
How Flies Are Linked to Damp Conditions
Drying up a puddle on the surface does not always address residue inside a drain, saturated soil beneath a leak, or organic debris trapped beside the foundation. Flies are drawn to moisture combined with organic materials. If the water table is high, there is more mingling of organic materials and water, attracting flies.
Around foundations, lingering water will wet leaves, causing them to decompose, providing flies with organic material, and then moving on to clog drains. Leaking pipes, soggy mulch, and poorly maintained trash areas can also create suitable conditions for flies. Northwest Indiana pest control services can address potential fly issues when routine cleaning and moisture corrections are not enough.
Manage Moisture and Pest Entry Points
Direct downspouts well away from the foundation, clean gutters, correct negative grading, repair leaks, and avoid piling mulch against siding. Keep foundation plantings trimmed enough to allow airflow, clear wet leaf debris, and store trash in closed containers.
