Not a horror story. But something creeps me out about these Langaws

Sobrang daming langaw sa bahay namin especially in the afternoon. It's not just ordinary langaw, they are quite aggressive. We have tried many repellants and aerosol sprays but none of those are effective.

The scary part is it seems everywhere we go sinusundan kami ng mga langaw. Kahit kumaen sa mcdo, jbee or any other restos nilalangaw kami literal.

A friend told me na baka daw kinukulam kami or what. Does anyone know any superstition about these langaw?
