Drastic times call for drastic measures
Many opinions states that the rat glue traps should be the last option when dealing with rats. Pretty inhumane, they still do a good job when rats learn to avoid the other traps and poisoned bait. The rats tend to be less suspicious when facing a glue trap, because of the lower profile of the object.
Like most of the traps and poisons, the rat glue trap must be set in the regular paths of the rodents, and near their nesting and feeding areas. The glue traps are also used in sensitive surroundings, where a quick catch is a priority, such as kitchens or medical environments to prevent contamination. The glue traps are commercialized in different sizes and depending on your necessities you should choose accordingly. First make a good setting plan by observing the rats habits and movement paths, then place the glue traps in proper places. Larger areas require larger glue boards, while smaller and tighter areas require smaller glue traps. Beware not to set mice glue traps since they are too small, facilitating the rat’s escape.
Many consider this method to be inhumane, since the rat is not killed instantly. Most of the times the rats die of stress (which leads to heart attack since small rodents are known to have extremely high heart rates), but they could also die of dehydration or suffocating (after gluing their faces on the boards). In other cases, the rat catcher is left with the job of killing the rat. In worst case scenarios, a glued rat will chew of their feet and fur in a desperate effort to escape, making it an difficult image to look at.
Two different presentations for rat glue traps are glue books and glue tunnel, which basically are what their names implies. The glue book opens exactly like a book, offering more flexibility for setting and placement, due to its unique design. The other one is a tunnel shaped glue trap, best used in dusty areas to keep the glue sticky for a longer period, and is also hiding the dead rat from sight.
