The easiest and most effective way to remove botfly larvae is to apply petroleum jelly over the location, which prevents air from reaching the larva, suffocating it.
It can then be removed with tweezers safely after a day.
White glue mixed with pyrethrin or other safe insecticides and applied to the spot of swelling on the scalp will kill the larvae within hours, as they must keep an air hole open, so will chew through the dried glue to do this, consuming the insecticide in the process.

Venom extractor syringes can remove larvae with ease at any stage of growth.
As these devices are a common component of first-aid kits, this is an effective and easily accessible remedy.
A larva has also been successfully removed by first applying several coats of nail polish to the area of the larva's entrance, weakening it by partial asphyxiation.
Covering the location with adhesive tape would also result in partial asphyxiation and weakening of the larva, but is not recommended because the larva's breathing tube is fragile and would be broken during the removal of the tape, leaving most of the larva behind.

Oral use of ivermectin, an antiparasitic avermectin medicine, has proved to be an effective and noninvasive treatment that leads to the spontaneous emigration of the larva.
This is especially important for cases where the larva is located at inaccessible places like inside the inner canthus of the eye.
