Female horseflies & deerflies hunt for people, horses and other livestock to drink blood for reproduction. The black ball of the flytrap imitates a prey this attracts them and catches them. The Loer H-trap horsefly trap is a Dutch design and tackles the problem with biting flies in a fast and natural way. We have a few brands of flytraps and also sell the original Sticky Trap glue to build your own flytrap. You can read more about it by the following link. 

The Sticky Trap Glue has been specially developed for catching horseflies around people and livestock. The Sticky Trap flytrap glue is used all over the world to reduce problems with biting and annoying horseflies in a natural way without the use of pesticides. Sticky Trap horsefly Trap Glue is made from natural minerals, light brown in colour, sticks for a long period (up to 20 weeks!) and will not attract pollinating insects such as bees and butterflies.

Household, black & stable flies are attracted by smell and taste and now you will think if we place a trap with smell and taste for example, a catch bag with a scent block that you will have good results... However, many who have tried this will find out that it does catch a lot but does not work very well. The enormous smell attracts many extra flies from outside. With Sticky Trap flytrap glue, you can build traps that work and catches the flies that are there already and stop the reproduction. Learn more by the following link.
