The answer to 'why is my termite bites' is that you likely do not have termite bites. Termites do not bite humans - they feed on wood and other cellulose materials in your home. The bites or skin irritations you are experiencing are most likely from other pests such as ants, bedbugs, or spiders.
If you are concerned about potential pest infestations in your home, it's best to have a professional pest control technician inspect your property. They can properly identify the pest causing the issue and recommend the appropriate treatment to eliminate the problem.
