To do a proper inspection first clear away any and all vegetation,debris,etc away from the house. If it's not part of the house it shouldn't be there anyhow. Next get your grubbies on cause you'll need to spend time on your knees. Examine closely the spaces between the siding and the slab or where the stucco meets the earth. These are primary entry points for moisture and insect intrusion. Make a note of any spots that need to be sealed and any insect evidence needs to be addressed as well. Termites are best left to the pros but you can handle ants and roaches yourself. If you can't tell the difference guess what? You're not alone and need the pros.
