wasp wont die!!!!!

this damn wasp has been in my house for five days now, jump scaring me every couple mornings when i water my plants. it has been DROWNED with wasp killer a whopping 3 (THREE!) times AND IT KEEPS COMING BACK. i would squish it but every time i spray it it disappears somewhere and i cant find it!! this morning i sprayed it only to find it crawling up a cord 2 minutes later, sprayed again, lost it.

im terrified of grabbing and squishing them. my boyfriend tells me to just do it and get it over with but i cant bring myself to. im too shaky. WHAT DO!?
