RavensGryf has indicated that some pest control companies utilize the Orange Oil method now which would be safe.
Call around and find one who will agree to use the method you desire.
A pest control service could eliminate the spider "nests" and traces of them that you've seen, spray the oil where necessary and your problems should be solved.
It was the pest control service that recommended the plugs. I told them I wished to take care of the problem without the usage of chemicals and stuff that could hurt my parrots and they said they could not provide that but there are these plugs that help bla bla bla
I live in a small city now and only found 2 pest control companies one of which said they don't really deal with spiders but provide help for other types of pests.
I have contacted the company that sells the product and I was told that has the frequencies of the product alternate between 30,000 and 60,000hz (to avoid the insect getting used to it) it won't affect any bird.
Some other pets like dogs and cats are capable of hearing high frequencies but this device does not bother them as the volume of the frequency is low and no different from the one emitted by many electronic devices we are not aware of.
I just did some digging at uni for lab reports regarding the correlation between bird's auditive system and ultrasonic sound to make sure they were not just trying to sell the product and it has been reported in all studies available that frequencies above 20khz (for some wild species, above 29khz) cannot be heard by them as they cannot be heard by us.
The company said I could try the product for a month and if it's not what I'm looking for I could give it back, therefore I am now at ease and will let you know if it's a potentially good method for pest control while having budgies and tiels
