I know that while living in the woods these things can't be totally prevented. What can I do to discourage them from coming in my house? It is one thing to be careful of these creatures when walking in the woods, it is quite another to wake up with some of the more inhospitable ones on or way too close to my pillow. ex. fire ants, huge spiders, copperheads (one killed 5 ft from where I lay my head at night), scorpions, etc. We have raked the yard and try to keep it clean with all leaves/debris away from the house. What more can I do? I am not able to sleep very well anymore.
