talked to my neighbor next door about this, she has a masters in zoology and a minor in herpatology. One earwig should not hurt him but, she also said that you should watch for parasites and mites not knowing where the thing came from. He also may or may not get a slightly watery poo from it. BTW she works for the Denver Zoo and is very knowledgable but for the most part watch him and try not to worry...he should be ok. hope this helps!
