How to Deal with Constant Mosquitoes at Home? Insect Expert Reveals One Method to Kill All Before They Enter

As summer heat brings more mosquitoes, a recent online recommendation for a mosquito-killing lamp from Costco has gained attention. Not only is the device simple and lightweight in design, but users have reported a noticeable reduction in household mosquitoes after use. It became so popular that it temporarily sold out during peak demand. Priced originally at 999 yuan, it can be purchased for just 785 yuan during promotional events, sparking public discussion.

A user posted in the Facebook group "Costco Product Experience – Honest Reviews" about their experience with the SABA mosquito trap lamp. Having seen others recommend it in the group and receiving personal endorsements from friends, they visited Costco only to find the entire stock sold out on their first attempt. After returning some time later and finding it restocked, they quickly bought one before the discount period ended.

The poster currently uses the lamp in their living room and notes that its appearance is simpler than expected, blending well into the home environment without being obtrusive. The unit is lightweight and can even be hung up, allowing them to move it around based on where mosquitoes tend to gather. After several days of use, flying mosquitoes have indeed become less frequent, reducing the need to chase them down with an electric swatter at night. They also report that the annoying buzzing near their ears has finally quieted down.

Following the post, many netizens shared positive feedback: "Works well—even catches small fruit flies," "Compact and effective against all sizes of mosquitoes; remote control makes operation easy. Used for nearly a month and still satisfied," "Placed on the first floor—second floor and above are now almost mosquito-free (used for almost a year)," "This one is super effective! Must buy during sales," and "The discounted price really makes a difference."

Don’t assume living on higher floors guarantees safety! Professor Tu Wu-Chun from the Department of Entomology at National Chung Hsing University points out that house mosquitoes excel at vertical movement through stairwells, elevators, and drainage pipes to invade upper floors. They are most active at night, and dark corners indoors, behind furniture, or even septic tanks in basements can serve as breeding grounds.

To combat this, the Environmental Protection Administration recommends sealing kitchen and bathroom drain outlets, installing nylon mesh screens, and using window screens and mosquito nets as physical barriers. These measures prevent mosquitoes while maintaining ventilation. Additionally, placing absorbent materials like sponges in the saucers under indoor potted plants can block mosquito egg-laying. Setting mosquito traps about 50 cm above the ground maximizes capture efficiency.

Leveraging mosquito behavior allows homeowners to naturally repel and trap them using light and scent. Since mosquitoes avoid orange-red light, replacing indoor bulbs with orange-tinted ones—or covering existing lights with translucent orange film—can create a chemical-free repellent effect by utilizing specific wavelengths.

Another low-cost method is the "sugar water trap." Place a small amount of sugar water or beer inside an empty bottle and set it in a dark corner. Mosquitoes are attracted by the sweetness and fermentation aroma, enter the bottle, but cannot escape. When combined with drain protection, this creates a comprehensive non-toxic anti-mosquito system.

Beyond commercial lamps, households can easily make highly effective DIY mosquito traps. Professor Tu shares a method using only a plastic bottle and black tape to create a trap that exploits mosquitoes’ phototaxis—luring them into a dark channel. Real-world tests show a capture success rate exceeding 90%. Each unit lasts about a week, and regular weekly cleaning and replacement maintain high efficiency. Alternatively, filling a simple bottle with water to trap mosquitoes achieves complete mosquito control without any chemicals.
