WEBVTT NOTE Paragraph 00:00:04.728 --> 00:00:07.368 In this video we illustrate for you some tips and tricks 00:00:07.368 --> 00:00:10.488 for placing the Cross-vane or Lindgren traps in the field. 00:00:10.888 --> 00:00:14.392 Although field placement instructions vary slightly for each pest survey, 00:00:14.392 --> 00:00:18.759 the consistent rule for these traps is they must always be hung at least high enough 00:00:18.759 --> 00:00:20.808 for the collection cup to clear the ground. 00:00:21.927 --> 00:00:24.584 Ideally you also want the traps as close to the target 00:00:24.584 --> 00:00:26.488 fields or storage areas as possible. 00:00:27.464 --> 00:00:29.897 Try to choose sites where it is unlikely people 00:00:29.897 --> 00:00:31.639 or animals could tamper with the trap. 00:00:32.216 --> 00:00:34.839 You will also want to be near the pest habitat 00:00:34.839 --> 00:00:38.280 because lure pheromones have a very short range beyond the trap. 00:00:39.191 --> 00:00:42.283 You will need to use either a sturdy rebar stake, 00:00:42.283 --> 00:00:44.391 or a strong tree to hang the trap from. 00:00:45.257 --> 00:00:46.840 It is important these are secure and 00:00:46.840 --> 00:00:49.848 able to withstand a variety of weather conditions. 00:00:51.015 --> 00:00:53.527 For rebar stakes, you should drive the stake into the ground 00:00:53.527 --> 00:00:57.656 a minimum of 6 inches to achieve the needed stability for hanging traps. 00:00:58.393 --> 00:01:03.048 If the soil is a loose type, the stake may need to be driven deeper. 00:01:03.656 --> 00:01:08.215 If using trees, select limbs with a diameter at least as wide as your forearm. 00:01:08.904 --> 00:01:12.183 The limb should also be fairly perpendicular to the tree 00:01:12.183 --> 00:01:15.656 to avoid the trap sliding down to the notch where branch attaches to trunk. 00:01:16.887 --> 00:01:20.263 Tall shrubs are not recommended as the branches are not strong enough 00:01:20.263 --> 00:01:23.287 to withstand the trap weight in addition to the weather. 00:01:23.427 --> 00:01:28.443 If you are surveying for forestry or other tree pests, you will generally 00:01:28.443 --> 00:01:32.889 want to hang these higher than can be reached without tools and some creative thinking. 00:01:33.655 --> 00:01:36.167 Here are a few tips for achieving the necessary height. 00:01:37.096 --> 00:01:38.888 One method for getting the trap up high 00:01:38.888 --> 00:01:42.167 is to use a long-handled, threaded telescoping pole. 00:01:42.839 --> 00:01:44.359 This could be a ceiling paint roller or 00:01:44.359 --> 00:01:49.306 a fiberglass extension pole ordered from an arbor specialty store such as this one. 00:01:50.373 --> 00:01:53.320 Attach the modified hook by screwing it onto the threaded end. 00:01:54.087 --> 00:01:56.695 This hook can be ordered through the pest surveillance catalogue. 00:01:57.864 --> 00:02:01.463 You will also need a special hook that will remain in the tree to hold the trap. 00:02:02.087 --> 00:02:04.569 This can also be ordered from the catalogue. 00:02:05.272 --> 00:02:08.088 Place the trap hook on the pole hook 00:02:08.088 --> 00:02:13.111 then stretch it up to the high point you are aiming for. 00:02:14.647 --> 00:02:16.344 When the trap is hanging where you want, 00:02:16.344 --> 00:02:19.736 push the trap hook down until it pops over the limb. 00:02:20.760 --> 00:02:23.322 Then twist the pole hook down and out of the trap hook 00:02:23.322 --> 00:02:25.288 leaving the trap behind. 00:02:26.943 --> 00:02:30.618 A second popular method for hanging tree traps is to use a throw bag. 00:02:31.592 --> 00:02:33.515 A small, but heavy bag is attached to 00:02:33.515 --> 00:02:35.847 a long rope and thrown over the desired limb. 00:02:36.617 --> 00:02:39.815 Use whatever knot works for you to attach the rope to the bag, 00:02:39.815 --> 00:02:43.145 But be sure the knot will not come loose when throwing the bag, 00:02:43.262 --> 00:02:47.593 or risk losing either the rope or the throw bag if it gets tangled in the branches. 00:02:48.664 --> 00:02:53.016 Please visit the webpage video links for a short tutorial on knot tying for tree work. 00:02:53.944 --> 00:02:57.047 Pick the limb you would like to hang the trap from. 00:02:57.047 --> 00:02:58.968 Make sure it is not higher than you can throw, 00:02:58.968 --> 00:03:00.634 and big enough to hold the trap. 00:03:01.576 --> 00:03:04.151 You also want to aim for a location on the branch that will 00:03:04.151 --> 00:03:07.671 be secure yet away from the notch where branch meets trunk. 00:03:08.522 --> 00:03:11.271 Make sure the rope is long enough to get over the height of the limb 00:03:11.271 --> 00:03:15.255 with enough length left to tie and anchor the trap around the tree. 00:03:16.087 --> 00:03:19.759 With the rope securely attached, throw the bag over the limb 00:03:19.759 --> 00:03:21.399 letting the rope trail behind it. 00:03:22.184 --> 00:03:26.616 If all goes well, the bag will drop to the ground on the other side of the limb. 00:03:26.616 --> 00:03:28.408 If it gets stuck in the understory, 00:03:28.408 --> 00:03:32.072 gently tug the rope to ease the bag back down to you and try again. 00:03:32.984 --> 00:03:35.543 Once the rope is well-placed, untie the throw bag 00:03:35.543 --> 00:03:37.623 and tie trap to the rope end. 00:03:38.727 --> 00:03:41.016 Again, be sure this knot is secure. 00:03:41.016 --> 00:03:44.760 Then hoist it up to the desired height. 00:03:44.960 --> 00:03:46.775 Do not let go of the rope. 00:03:46.775 --> 00:03:50.264 If you let go, the trap will drop and you may have to start all over. 00:03:50.264 --> 00:03:53.845 Tie the rope to the tree to anchor your trap. 00:03:53.885 --> 00:03:56.745 We recommend using a quick release knot. 00:03:56.745 --> 00:04:01.063 Whatever knot you choose, it should not be in danger of coming undone on its own. 00:04:01.672 --> 00:04:04.951 However, if your knot becomes too tight and you can’t untie it 00:04:04.951 --> 00:04:07.752 at the end of the survey, then you will need to cut the rope. 00:04:08.982 --> 00:04:12.344 Cutting the rope results in the trap crashing to the ground 00:04:12.344 --> 00:04:14.455 and potentially losing many of your samples. 00:04:15.768 --> 00:04:18.472 We hope these tips for hanging pest traps are helpful. 00:04:18.951 --> 00:04:22.055 Please modify them as needed for your situation 00:04:22.055 --> 00:04:23.773 and specific survey needs.
