Yes. In Jainism, ahimsa (non-violence) extends to all living beings, big or small, including insects like mosquitoes. Liberating or protecting a mosquito when it is threatened by a spider aligns with the aim of minimizing harm. The preferred approach is to avoid harming them and to use non-lethal methods (like nets, repellents, or gentle interference) rather than killing. Only in cases of real, imminent danger to human life would one carefully weigh the least-harm option.

Notes:

• Both Digambar and Śvetāmbara traditions uphold ahimsa as central; there is no major sectarian difference in this everyday guidance about harming insects.
• The emphasis is on reducing harm overall and practicing prudent, non-lethal means wherever feasible.
