Main challenges
- Summer heat — heat-stress precautions needed in Jul–Aug
- Barber pole worm — long warm-wet parasite season (May–Sep)
- Meningeal worm — white-tailed deer parasite is established in this region
- Hard winters — average lows under 15 °F in Jan–Feb
- Low selenium — regional soils and hay tend to be selenium-deficient
Overall rating: 71/100 — Good on our alpaca climate comfort score. Climate type: Warm-summer humid continental (Köppen Dfb).

Key recommendations
- Shearing: May.
- Best months for crias to be born: May–Jun (breed in Jun–Jul).
- Heat precautions: Jul–Aug.
- Barber pole worm season: May–Sep — run fecal egg counts every 4–6 weeks in these months.
- Freezing nights: Nov–Mar — keep water from freezing.
- Vitamin D for crias: Oct–Mar.
- Grazing season: May–Oct (about 6 months); feed hay the rest of the year.
- Meningeal worm: Meningeal worm (carried by white-tailed deer) is established in this region and is a leading cause of neurological disease in alpacas. Talk to your vet about a prevention plan for the snail season.
- Selenium: Soils and hay in this state are often selenium-deficient. Use a camelid mineral formulated for low-selenium areas and blood-test a few animals each year.
