Yes but phobias can be overcome, i.e. challenging our conditioning.  I did just this!
I was staying overnight at a country cottage.  The bed I was allocated had a huge spider very high above the pillow area, on the ceiling!   Then and there I knew I had to come to terms with this if I were to sleep.  I asked myself what I was afraid of.  Simple - that it would land on my face!  I then asked myself had this ever occurred?  No.  So I overcame it with logic!
When I see a spider now, e.g. crawling on the floor, I employ the card and glass trick - capture it and fling it outside.  No reason that they should lose their life just through a silly, learnt fear!
