Can humans affect the jinn?
Yes, humans may affect the jinn and that is why the Prophet (Peace be upon him) informed us about the food of the jinn, which are the bones and dung of animals. Thus, there is an interaction between our world and the world of the jinn.
The world of the jinn is an independent and separate world, with its own distinct nature and features, which are hidden from the world of humans. Jinn and humans have some things in common, such as the possession of understanding and the choice between the way of good and the way of evil. The word jinn comes from the Arabic root meaning “hidden from sight”.
Allaah says (interpretation of the meaning):
“… Verily he [Shaytaan] and his qabeeluhu [his soldiers from the jinn or his tribe] see you from where you cannot see them…”
The jinn eat and drink. Ibn Mas’ood (May Allah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: "Someone from among the jinn called me, and I went with him and recited Qur’aan for them." He took us and showed us the traces of where they had been and the traces of their fires. They asked him for food and he said, "You can have every bone on which the name of Allaah has been mentioned that comes into your possession, as meat, and all the droppings as food for your animals." The Prophet (peace and blessings of Allaah be upon him) said, "So do not use [these things] for cleaning yourselves [after relieving oneself], for they are the food and provision of your brothers."
According to another report, “A delegation of jinn from Naseebeen came to me, and what good jinn they are! They asked me for food and I prayed to Allaah for them, so that they would not pass by bones or droppings, but they would find food on them.” 
The believing jinn may eat any bone on which the name of Allaah has been mentioned, because the Messenger (peace and blessings of Allaah be upon him) did not permit them to have anything on which Allaah’s name has not been mentioned – those are for the kuffaar among the jinn.
According to the hadeeth narrated by Ibn Mas’ood, that we have quoted above, the jinn asked the Messenger (peace and blessings of Allaah be upon him) for provision, and he said to them: “…and [you can have] all the droppings as food for your animals.”
The jinn live on this earth where we do. They are mostly to be found in ruins and unclean places like bathrooms, dunghills, garbage dumps and graveyards. Hence the Prophet (peace and blessings of Allaah be upon him) taught us to take precautions when entering such places, by reciting the adhkaar (prayers) prescribed by Islam. One of these was reported by Anas ibn Maalik (may Allaah be pleased with him), who said: “When the Messenger of Allaah (peace and blessings of Allaah be upon him) entered the toilet, he would say,
"Allaahummainneea’oodhubika min al-khubuthiwa’l-khabaa’ith (O Allaah, I seek refuge with You from the evil ones, male and female)."" 
Al-Khattaabi explained that khubuth is the plural of khabeeth (evil or dirty – masculine form), and khabaa’ith is the plural of khabeethah (evil or dirty – feminine form), and that what is meant is male and female shayaateen.
