Evansville sits in a bend of the Ohio River in the far southwest corner of Indiana, closer in climate to Kentucky than to Chicago. Summers are long, hot and humid, winters are milder than most of the state, and the river keeps the air damp. A floodwall protects the downtown riverfront, and a lot of the city's older housing sits on low, flat ground where moisture lingers. That climate gives pests a head start in spring and keeps them going well into fall.

Pests Evansville residents report
- Eastern subterranean termites, widespread in southern Indiana and active in humid soils.
- American cockroaches in basements, drains and sewer-connected areas, plus German roaches in apartments and restaurants.
- Brown recluse spiders, which occur in southern Indiana and hide in storage areas and quiet corners.
- Mosquitoes near the Ohio River, Pigeon Creek and low-lying yards, with ticks in wooded areas such as Wesselman Woods' edges.
- Carpenter, pavement and odorous house ants from spring onward.
- Norway rats and house mice in older city blocks and near commercial areas.
- Stink bugs, lady beetles, wasps and hornets in the warm seasons.
What Evansville's housing means for pests
The Riverside Historic District, Lamasco and the streets around Haynie's Corner include early-twentieth-century brick and frame houses, bungalows and narrow lots, many with basements or crawlspaces. Mid-century ranch homes spread out toward the east and north, often on slabs. Newer subdivisions in Newburgh and on the north side border farmland and woods. Each type brings its own openings: crawlspace moisture, slab cracks, mature trees overhanging rooflines and field edges full of mice.
Season by season
- Spring: termite swarms, ant trails and early mosquitoes.
- Summer: peak roach, wasp and mosquito activity, with spiders on porches and in sheds.
- Fall: stink bugs, lady beetles and mice press toward warmth.
- Winter: milder cold lets some pests stay active, and rodents nest in walls.
How providers help
A licensed technician inspects the foundation, crawlspace, attic and yard, then chooses methods to match: perimeter service for general pests, bait or soil treatment for termites, trapping and sealing for rodents, and sticky monitors and dusts for spiders. A good provider also points out moisture and structural fixes that reduce repeat problems.
Flood-season notes
Evansville has a long history with the Ohio, and even without a major flood, spring rains can overwhelm drains and saturate yards. After such events, check basements and crawlspaces for standing water, dry them out quickly, and watch for roaches, rodents and mosquitoes that move in as the water recedes. Discard soaked cardboard and insulation, which hold moisture and shelter pests.
Prevention suggestions
- Run a dehumidifier in basements and keep crawlspace vents clear.
- Keep mulch, wood and soil off siding and foundations.
- Remove standing water in flowerpots, tires and gutters.
- Store items in sealed plastic bins rather than cardboard.
- Screen vents and seal openings around pipes.

Frequently asked questions
Are brown recluse spiders in Evansville?
They occur in southern Indiana. Reducing clutter and using monitors helps manage them.
Why are there so many roaches near the river?
Humid air, aging sewer lines and warm basements suit American roaches particularly well.
How common are termites here?
Quite common. Annual inspections are a sensible habit.
Does the floodwall affect pests?
Not directly, but flood and heavy rain events can displace rodents and insects into buildings.
