This listing is for 5 Treated Monarch Eggs. I use a bleach solution that will rid the egg of the OE PARASITE. The OE causes CRINKLED WING SYNDROME and will kill the caterpillar. They will sometimes still hatch and be perfectly fine, but they will pass on the parasite to their babies. That is why the eggs are bleached to rid the egg casing of the disease. There is a chance that if the shipping is delayed that the egg could hatch. So I always pack with plenty of food to eat during their journey.
