Most Common Insects In Kansas
This section covers the top insects you will encounter in Kansas. Each one has a unique role in the ecosystem, and we will break down what they look like, where they live, and how to handle them.
House Flies
House flies are everywhere in Kansas. They breed in garbage, animal waste, and rotting food. You will see them buzzing around kitchens, barns, and outdoor picnics.
- Appearance: Gray bodies with four dark stripes on the thorax
- Size: About 6 to 7 millimeters long
- Behavior: They feed on liquid food and can spread diseases
- Control: Keep trash sealed and clean up spills quickly
These flies are more than just annoying. They can carry bacteria like Salmonella and E. coli. To reduce them, use screens on windows and doors.
Mosquitoes
Mosquitoes are a summer nuisance in Kansas. They breed in standing water, so after a rainstorm, their numbers can spike. The most common species here is the Culex mosquito, which can carry West Nile virus.
- Appearance: Slender bodies with long legs and a proboscis
- Size: 3 to 6 millimeters
- Behavior: Females bite for blood, males feed on nectar
- Prevention: Remove standing water from bird baths, gutters, and buckets
You can protect yourself by using EPA-approved repellents and wearing long sleeves at dawn and dusk. Mosquitoes are most active during these times.
Ants
Ants are among the most common insects in Kansas. You will find several species, including carpenter ants, pavement ants, and odorous house ants. Each type has different habits.
- Carpenter ants: Large, black, and they nest in wood
- Pavement ants: Small, brown, and they build nests under sidewalks
- Odorous house ants: Tiny, dark, and they smell like rotten coconut when crushed
To control ants, seal cracks in your foundation and keep food in airtight containers. If you see a trail, follow it back to the nest and apply bait.
Ladybugs
Ladybugs are beneficial insects. They eat aphids and other garden pests. In Kansas, the most common species is the convergent lady beetle. They are bright red with black spots.
- Appearance: Round, dome-shaped bodies with spots
- Size: 5 to 8 millimeters
- Behavior: They hibernate in large groups during winter
- Benefit: Natural pest control for gardens
If you find ladybugs inside your home, they are likely looking for warmth. Vacuum them up gently and release them outside.
Grasshoppers
Grasshoppers are a classic sight in Kansas fields. They can be a problem for crops, especially during dry years. The differential grasshopper is one of the most common species here.
- Appearance: Long bodies with powerful hind legs for jumping
- Size: 20 to 40 millimeters
- Behavior: They feed on grasses and crops
- Control: Use insecticidal soap or neem oil on plants
Grasshoppers are most active in late summer. If you have a garden, cover your plants with row covers to protect them.
Boxelder Bugs
Boxelder bugs are black with red markings. They are common around boxelder trees, but they also invade homes in the fall. They do not cause structural damage, but they can be a nuisance.
- Appearance: Flat, oval bodies with red lines on the wings
- Size: 11 to 14 millimeters
- Behavior: They gather in large numbers on sunny walls
- Control: Seal cracks around windows and doors
If they get inside, use a vacuum to remove them. Avoid squashing them because they can leave a stain.
Stink Bugs
The brown marmorated stink bug is an invasive species that has become common in Kansas. They are shield-shaped and release a foul odor when disturbed.
- Appearance: Brown with lighter bands on the antennae
- Size: 14 to 17 millimeters

- Control: Use pheromone traps and seal entry points
Stink bugs can damage tomatoes, peppers, and soybeans. If you find them in your garden, handpick them and drop them into soapy water.
Japanese Beetles
Japanese beetles are a serious pest for lawns and gardens. They have metallic green bodies and copper wings. They feed on over 300 types of plants.
- Appearance: Shiny green with copper-colored wing covers
- Size: 8 to 11 millimeters
- Behavior: They skeletonize leaves by eating the tissue between veins
- Control: Apply milky spore to your lawn to kill grubs
These beetles are most active in June and July. You can trap them, but be careful because traps can attract more beetles to your yard.
Earwigs
Earwigs look scary because of their pincers, but they are mostly harmless. They are common in Kansas gardens and under rocks or mulch.
- Appearance: Dark brown with a pair of forceps at the rear
- Size: 12 to 15 millimeters
- Behavior: They are nocturnal and feed on decaying matter
- Control: Reduce moisture around your foundation
Earwigs can damage seedlings and soft fruits. To control them, set out rolled-up newspapers as traps and dispose of them in the morning.
Bees And Wasps
Bees and wasps are vital for pollination. In Kansas, you will see honeybees, bumblebees, and paper wasps. They are different from each other in behavior and appearance.
- Honeybees: Fuzzy, golden-brown, and they live in large colonies
- Bumblebees: Large, black and yellow, and they nest in the ground
- Paper wasps: Slender, with long legs, and they build open nests
If you find a nest near your home, call a professional to remove it. Do not try to remove it yourself, especially if you are allergic.
Fleas And Ticks
Fleas and ticks are common in Kansas, especially if you have pets. They can carry diseases like Lyme disease and Rocky Mountain spotted fever.
- Fleas: Tiny, dark, and they jump onto hosts
- Ticks: Flat, oval bodies that swell when feeding

Crickets can damage fabrics and paper products. If they get inside, use sticky traps to catch them.
How To Manage Common Insects In Kansas
Now that you know the most common insects in Kansas, here are some practical tips to manage them. These steps will help you keep your home and garden safe.
Prevent Entry Into Your Home
The best way to deal with insects is to keep them out. Follow these steps:
- Seal cracks around windows, doors, and foundations
- Install screens on all windows and vents
- Use weather stripping on doors
- Keep firewood away from the house
Check for gaps regularly, especially after storms. A small crack can let in hundreds of insects.
Reduce Moisture Around Your Property
Many insects are attracted to moisture. Fix leaky faucets and pipes. Make sure gutters drain away from the foundation.
- Remove standing water from bird baths and flower pots
- Trim bushes and trees away from the house
- Use dehumidifiers in basements and crawl spaces
Dry conditions make your home less inviting to pests like silverfish and earwigs.
Use Natural Predators
Encourage beneficial insects like ladybugs and praying mantises. They eat aphids, caterpillars, and other pests.
- Plant flowers that attract beneficial insects
- Avoid broad-spectrum pesticides
- Release ladybugs in your garden
Natural predators help keep the ecosystem balanced without chemicals.
Apply Pesticides Safely
If you need to use pesticides, choose ones that are targeted. Read the label carefully and apply them only where needed.
- Use bait stations for ants and roaches
- Apply insecticidal soap for soft-bodied insects
- Use diatomaceous earth for crawling insects
Always wear gloves and a mask when applying chemicals. Keep children and pets away until the area is dry.
