Key recommendations for Maryland
- Shearing: April.
- Best months for crias to be born: Apr–Jun (breed in May–Jul).
- Heat precautions: Jul–Sep.
- Barber pole worm season: Apr–Oct — run fecal egg counts every 4–6 weeks in these months.
- Freezing nights: Dec–Feb — keep water from freezing.
- Vitamin D for crias: Nov–Feb.
- Grazing season: Apr–Nov (about 8 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.

Frequently asked questions
Can you raise alpacas in Maryland?
Yes. Alpacas are kept successfully in most climates with good management. Maryland scores 69/100 (good) on our alpaca climate comfort scale; the key issues are summer heat, barber pole worm and meningeal worm.
Which part of Maryland is best for alpacas?
By our climate comfort score, the most alpaca-friendly counties are Garrett County, Carroll County and Allegany County; the most challenging are Anne Arundel County, Caroline County and Charles County.
When should alpacas be shorn in Maryland?
Plan shearing for April, once nights stay above about 38°F (3°C) but before summer heat builds.
What is the best time for crias to be born in Maryland?
Mild months suit newborn crias best — here that is Apr–Jun. For births then, breed females in May–Jul (gestation is about 335 days).
How much hay does an alpaca need per year in Maryland?
With roughly 4 months of little or no grazing, plan on about 632 lb (287 kg) — around 13 small square bales — per adult alpaca per year, plus waste.
How hot does it get for alpacas in Maryland?
Heat-stress precautions are needed in Jul–Sep. We estimate about 21 days a year above 90°F (32°C).
