Moth Populations on the Rise Across Kansas After Mild
WICHITA, KANSAS — If you’ve noticed more moths fluttering around porch lights and windows this fall, you’re not imagining things. Kansas is experiencing a noticeable rise in moth populations, and experts say it’s largely due to this year’s mild, rainy summer that created near-perfect conditions for the insects to thrive.
Warm, Wet Weather Encouraged Moth Boom
According to Entomologist Ryan Cocking, Technical Director at Patton Termite and Pest Control in Wichita, the state’s recent weather patterns have played a major role in the sudden increase.
“I think this year has been a mild summer with a lot of rain, so it’s just been very good conditions for them to flourish,” Cocking explained.
The combination of warm temperatures and frequent moisture boosted vegetation and insect activity — both of which support moth populations during their breeding cycles.
Migratory Moths Moving South for Fall
Experts say the moths currently swarming around Kansas homes are migratory species making their seasonal journey south as temperatures drop.
Matt McKernon, an Ornamental Horticulture Agent with Sedgwick County K-State Research and Extension, said these moths are typically temporary visitors.
“A lot of the moths that we are seeing right now are migratory moths that are moving through our area and moving further south as temperatures cool off for the fall,” McKernon said.
While the insects may seem like a nuisance, specialists emphasize that they’re mostly harmless and should disappear once colder weather sets in.
Simple Ways to Reduce Moth Activity at Home
Entomologists suggest a few easy steps to minimize moth encounters until the seasonal shift clears them out naturally:
- Turn off exterior lights when not needed, as moths are strongly drawn to bright light sources.
- Treat lawns and gardens next spring to reduce egg-laying areas and larval development zones.
- Seal windows and doors to prevent moths from entering your home at night.
Most moths have short lifespans of just 15 to 30 days, meaning the current surge is expected to fade quickly with the arrival of colder air.
As Kansas transitions into late fall, experts say residents can look forward to fewer late-night fluttering visitors — at least until next year’s weather patterns determine whether the trend will return.
