ticks in lipa noi (no pet but my mom dog)

I dont have pet but my mom have dog, Bingo, mixed breed. He live in the house in Lipa Noi and every rainy season I find tick on my bed. Very disgusting, yuck. I help mom to check Bingo every evening after walk on the grass. Look at ears and between toes, the tick like to hide there. Spray is not enough, you need proper tablets from the vet, my mom did not know this. Also wash the bed sheet hot, even if you think is clean.
