Debugging the Tent Before Sleep

On my first solo camp and I’m loving it! I was moaning because I brought too much stuff but now that I’m all set up and happy… it was worth it. Here’s my question, the mosquitos, ants and daddy long legs seem determined to sleep with me. What’s your technique for debugging the tent for sleeping. And if you say a bug zapper please tell me what brand and model. The one I have just seems to be a pretty purple light.
