Does freezing kill the eggs of parasites?

Freezing can kill some parasite eggs, but its effectiveness depends on the type of parasite and the freezing conditions. Generally, temperatures below -20°C (-4°F) for several days can be effective in killing certain eggs, while others may be more resistant. It's important to note that not all parasites are equally affected by freezing, so additional methods of control may be necessary for complete eradication.
