The Most Common Explanation: Fungi or Slime Mold
One of the most frequent causes of white, round balls in the yard is fungal growth, especially after rain or high humidity.
Some mushrooms start as small white balls, often called “eggs”
Slime molds can look like clusters of foam or soft spheres
They often appear overnight and can disappear just as quickly
Although they may look alarming, these fungi are generally not dangerous to people or pets if left alone.
Another Possibility: Snail or Slug Eggs
In damp areas of the yard, especially near mulch, plants, or shaded soil, the white balls may be snail or slug eggs.
Key signs:
Smooth, round, pearl-like appearance
Found in clusters
Usually buried slightly under soil or debris
While not harmful to humans, they can lead to more garden pests if left untreated.
Could It Be Insect Eggs?
Some insects lay eggs that appear white or pale and spherical. These are usually found near plants or under leaves rather than out in the open.
Most insect eggs are harmless and part of the natural ecosystem, but gardeners may choose to remove them if they threaten plants.
Why They Appear Suddenly
These objects often show up after:
Heavy rain
High humidity
Warm temperatures
