Glue traps are a great way to monitor pest activity and catch some unwanted bugs. They use no toxic pesticides and they are inexpensive to use.
Bright yellow glue traps are the most attractive to flying insects. Place sticky traps close to garden plants to catch aphids, whiteflies, leafhoppers, fungus gnats, and thrips. Hang the sticky traps a foot or two away from the plants so they don't get tangled in the leaves, but close enough for the bugs to reach them. If you are hanging traps outside, don't hang them too close to doors or windows or you might draw insects inside. Hang the trap where the insects can clearly see the bright yellow color.
If you use glue traps inside the house to catch ants, cockroaches, spiders, or flies, place the traps where the pest is likely to travel. Cockroaches stay very close to walls and prefer dark corners so you will want to place traps in closets, under sinks, in corners of the room, behind the fridge, or in cupboards. It is a little known fact that roaches like high up places, so you might try placing traps on top of the fridge or cabinets, as well.
For ant trapping, place traps where you see ants or spiders frequently. By placing a lot of traps you can determine how extensive your infestation is and where the ants most frequently wander.
Glue traps are non-toxic and safer to use around humans and pets. You can even make your own sticky traps! Here's how:
1) Take a piece of thick yellow construction paper and cut it into 5 by 7 rectangles.
2) Either buy an insect trap coating like Tanglefoot Brand Pest Barrier or Tack Trap, or use old motor oil or petroleum jelly. You could also make an adhesive using a quart of corn syrup and a quart of water. Simply combine the water and corn syrup and boil it until it makes a sticky paste.
3) Take a plastic knife or piece of wood and spread your sticky substance onto the construction paper. If you are placing the traps on the floor, only spread it on one side, of course. If you are hanging the traps, then spread the glue on both sides.
4) Use a bent paper clip and a piece of string or wire to hang the sticky trap.
If you want to entice more insects to your sticky trap, add a piece of ripe fruit or some brown sugar to the surface. Place the fruit or sugar in the middle of the trap and watch the insects flock to it.
You will have to hang a lot of traps to get rid of large insect infestations, but glue traps will help reduce the number of insects and tell you where they are coming from.
Note: Using glue traps to trap rodents may not be your best choice. Rodents often escape from glue traps. Those that do not escape can suffer needlessly. We recommend using snap traps for rodent control when possible.
