Review: These plug ins are marvellous - *UPDATE October 20th 2023* I wanted to edit my review to say since we have used the plug in + refills, we have had no bites. Today I have ordered another one for the upstairs. There are a lot of small black flies around, they are around all the time, more so with the humidity. These little flying insects do bite, as do mosquitos. My bedroom downstairs is still working well, and I have been keeping mine on day and night. The refill won’t last as long doing it this way, but the cost is nothing compared to risking a hospital visit for us. I still highly recommend them, and still continue to have the refills on subscribe and save. I feel these are excellent and do the trick. β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€” My first initial review….. Considering my husband is allergic to any bites, from house flies, mosquitos, it’s a nightmare to get anything to work. Because epipens do not last long, we had to find something that works in our home. The sad fact is, bites are very serious for my husband and over the past few weeks have seen an increased amount of mosquitos because of the rain, climate, and humidity. I am 100% saying these plug ins work. The images you see of my husband were taken two days because I sent off for the plug in, it was our last resort. That morning he was bitten six times on the eye lid, and cheek, it was awful. Every night he takes antihistamines, good job he did, otherwise I hate to think what he would look like. Thank goodness this pushed me into getting a plug in, never used one before, except abroad, I never thought about these in my own home. My husbands face is back to normal now, before the plug in I was bitten six times on the arm, the images you see is going down now. I wanted to show the images just to say how much these plug ins have helped us both, now with climate change, there are so many mosquitoes, flies, ants, goodness knows what, they are always in the home. When the plug in arrived I de bugged my bed, washed everything and cleaned my carpets and washed the curtains. When the plug in arrived, it does stated to turn off in the day, and leave on through the night. I wanted to leave my plug in for the first two days on all day and night. The days and nights that followed neither of us had any bites, so far so good. The actual plug in at review was around Β£11.99 and refills Β£5.99 at review. I have the refills on subscribe and save now, for my husband at least, these save him from a trip to the hospital each time. I can honestly say this make mosquito and fly plug in is exceptional, and have the proof that these do work. We are 100% recommending these plug ins, especially for people who have allergies. ⭐️Thank you to the seller ⭐️I hope my review helps you. Review: Good - Work well.
