I wanted to ask if anyone knows the effectiveness of gazebos that have mosquito netting. The products that are out there seem quite expensive and before I buy on for our family and 8 month old baby I wanted to ask if they actually work?????  Does anyone have personal experience with this product? Most come with mosquito netting attached to hooks and a track. There seems to be a gap of about 1/2 inch between the netting and the track... can't the mosquitos get into the gazebo through these gaps??? Please advice if it is worth the cost of getting this for day and evening use. Thanks.
