Raid Electro Liquid Mosquito Repellent Loses Effectiveness Quickly

We bought the Raid Electro Liquid Mosquito Repellent, and it worked well for the first few days. However, last night, a mosquito was in the room, and despite having the Raid plugged in, it didn't keep the mosquito away. The product claims to provide 45 days of protection, but there are times when it simply doesn’t work. It would be great if Raid could develop a more effective formula that consistently delivers on its promise of long-lasting protection. We rely on this product to keep mosquitoes away, especially at night, and expect it to perform as advertised.
