Code Refactoring issue - cocos2d-iphone

Question

I have game ready and now I am trying to refactor code. I have derived Spider class from CCNode and used targeted delegate method CCTargetedTouchDelegate.
#interface Spider : CCNode<CCTargetedTouchDelegate> {
CCSprite* spiderSprite;
NSString * spiderKilled;
int killed;
AppDelegate *del;
}
+(id) spiderWithParentNode:(CCNode*)parentNode;
-(id) initWithParentNode:(CCNode*)parentNode;
#end
On Touch spider should be killed and here goes the code:
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
CGPoint tch = [touch locationInView: [touch view]];
CGPoint touchLocation = [[CCDirector sharedDirector] convertToGL:tch];
// Check if this touch is on the Spider's sprite.
BOOL isTouchHandled = CGRectContainsPoint([spiderSprite boundingBox], touchLocation);
if (isTouchHandled)
{
j = j + 1;
killed ++;
[del setKilledScore:j];
[self removeChild:spiderSprite cleanup:YES];
}
return isTouchHandled;
}
I am adding 10 spiders in GameScene layer using: -
for(int i=0; i <10 ;i++){
[Spider spiderWithParentNode:self];
}
But, unfortunately I am not able to remove spiders and giving me EXC_BAD_ACCESS error on this line: [self removeChild:spiderSprite cleanup:YES];
Please help me overcome this error.
Thanks
Update --
Spider Init code
// Static autorelease initializer, mimics cocos2d's memory allocation scheme.
+(id) spiderWithParentNode:(CCNode*)parentNode
{
return [[[self alloc] initWithParentNode:parentNode] autorelease];
}
-(id) initWithParentNode:(CCNode*)parentNode
{
if ((self = [super init]))
{
[parentNode addChild:self];
del = [[UIApplication sharedApplication] delegate];
CGSize screenSize = [[CCDirector sharedDirector] winSize];
spiderSprite = [CCSprite spriteWithFile:#"spider.png"];
spiderSprite.position = CGPointMake(CCRANDOM_0_1() * screenSize.width, CCRANDOM_0_1() * screenSize.height);
[self addChild:spiderSprite];
// Manually add this class as receiver of targeted touch events.
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:-1 swallowsTouches:YES];
}
return self;
}

If you manually add the class to the CCTouchDispatcher list, you should remove it from there after you're done using it.
