You want to place multiple traps between a woods line and your young pecan trees. You want to look at your traps each day. After a week, re-fill hole with denatured alcohol; it will evaporate out of there.<\/p>\n<p><strong>Ambrosia Beetle Control<\/strong><\/p>\n<p>Remember, all we are trying to do is note their first flight. <em>The beetles are attracted to the trap because when a caterpillar eats a pecan leaf, the tree emits an ethylene pheromone.<\/em> <strong>Once you see &#8220;toothpicks&#8221; on the trap, the beetles are out, and you can spray your pecan trees with a pyrethroid.<\/strong> When trees are young, the beetles can bore into the undeveloped bark. Once trees get a thick bark (about 5 or 6 years old), the beetles won&#8217;t bore into them.<\/p>\n<figure id=\"attachment_288\" aria-describedby=\"caption-attachment-288\" style=\"width: 768px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-288\" src=\"https:\/\/site.extension.uga.edu\/wilcoxcoag\/files\/2018\/02\/AmbrosiaBeetleTraps-003.jpg\" alt=\"\" width=\"768\" height=\"1024\" srcset=\"https:\/\/site.extension.uga.edu\/wilcoxcoag\/files\/2018\/02\/AmbrosiaBeetleTraps-003.jpg 768w, https:\/\/site.extension.uga.edu\/wilcoxcoag\/files\/2018\/02\/AmbrosiaBeetleTraps-003-225x300.jpg 225w, https:\/\/site.extension.uga.edu\/wilcoxcoag\/files\/2018\/02\/AmbrosiaBeetleTraps-003-104x138.jpg 104w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption id=\"caption-attachment-288\" class=\"wp-caption-text\">Place trap along wood edge about waist high<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>I was out with Mr. Larry Gibbs yesterday, and he and I made some ambrosia beetle traps to monitor ambrosia beetles\u00a0for his young pecans.
