@Jerry Delsol I currently have a flea infestation in my bedroom. I saw one of these Hemiptera and I was hoping that maybe this was a natural predator to a flea and I was happy to see the bug. The bug felt me breathing and felt my vibrations and did not go in the opposite direction and he came straight towards me. I was shocked and I neared my finger to it and it felt no fear. I climbed on my finger. I wanted to see if the Hemiptera would harm me and he went to the soft part of my hand between my palm and my thumb and then I saw that it had the "sword". It took a few seconds but then I felt a small prick. I was not happy but I decided that maybe it was a mistake the bug had made so I gave it a second chance. From my slight anger my hands started sweating. It climbed to my pinky finger where the skin was soft and it once again readied the sword and this time It inserted it ( i was watching through my jewellers magnifier by now ) and it inserted even further and I felt nerve pain. I decided that the Hemiptera is harmful to humans so I grabbed a tissue and crushed it. I am a vegetarian because I feel for animals, however I kill mosquitoes, now fleas, and also now hemiptera. I love spiders but in my new apartment there are none and that is probably why there is a flea infestation.
