Magnet Fly Elegant"

"Magnet Fly Elegant" is an elegant closed-type "magnet trap" for house flies (Musca domestica) and other flying insects (odorless and insecticide free).
Heat and light attract flies and insects to the windows, and, thanks to the closed design of the trap, invading insects stick to interior surfaces, remaining invisible to the human eye.
Instructions for use.
Remove the protective strip from the back of the trap and attach it to the glass in the corner of the window (this is how the trap works most effectively).
The trap will work until the entire inner surface is covered with insect bodies or dust.
