I'm one of those unfortunate individuals mosquitoes find SUPER attractive. I have to wear long pants and long-sleeve shirts outdoors. They know that there's delicious meal (my blood) inside my house, so they enter at every opportunity. At my computer I'm helpless. I'll have four or five bites before I'm able to react. Watching TV, I wrap a blanket around my body chin to toes. I still get bites. If I don't ice them down immediately, each turns into an enormous welt. Only antihistamine keeps me from going mad. I purchased the GLOUE Indoor Bug Zapper, frankly, because it was one of the lease expensive (important for a retiree) products, but also because it had great reviews. Now, this is going to sound like I've been paid to say it, but I have not had a single bite inside my house since the day I installed them! I swear to all things holy, I'm telling the truth. I just hope this helps some other poor soul to find the sweet relief I've found.
