According to my research, ants and deer antler tips are not kosher.
?Every year males in the deer family shed their large antlers and grow
a new set. The ability to re-grow something so large year after year
so quickly is unique in nature and is an example of the wonders of our
Creator. As these antlers grow, increased blood flow helps form
cartilage which is covered by soft velvety fur. The antlers then begin
to harden and transform into bone, similar to a shofar. At the time
when the antler is rich in nutrients, it is harvested from the deer
and processed into a powder supplement. The velvet is also extracted
to form Pantocrin found in anti-aging and athletic performance
products. All deer velvet is derived from the cartilage of animals
that have not been slaughtered. Therefore, this product is not kosher
as it is aiver min hachai. In addition, the blood content would also
prohibit this product.?

Insects and rodents
?Rodents, worms, amphibians, and creeping, swimming, or flying
insects, are not kosher. Fruits, vegetables, or grains are not kosher
when worms, insects, ants or mites are present on or in the item.?
