Simple earwig traps - review

April 19th, 2010
Driftwood Farm | Blog

Not long after the earwigs went to town in the greenhouse, they started causing havoc in the rows.    As I’ve been looking for ways to control the damage, I’ve often read cautions that the insects are most often beneficial, or at least, harmless.  This includes the book I most often consult for organic ways to deal with pest and disease problems.  (I would agree with this -  is so interesting that neither Matt nor I have had this type of problem with earwigs before.  But we clearly have a serious imbalance and need to deal with it.)

Young kale, some lettuce, about 90% of the just-sprouting radishes, and the strawberries were really hit hard over the course of a day or so, and I knew we had to do something before planting replacements, or anything new.  So, I decided to trial 3 methods of trapping earwigs at once, and see which worked the best.  The ideas came from various resources. 

What I learned:  There are WAY more earwigs here than I realized there were.  Loads.  Tons.

The three traps I am using are:  rolled up newspaper, damp newspaper stuffed into a container, and a pitfall trap with bait.

For all of the traps - place them in areas where you already have damaged plants.

Damp newspaper in container (3rd place)

How to:  dampen crumpled newspaper and stuff it into an old container of some sort (planter, etc.)  I used large yogurt containers.  Prop it up on a rock or stick so the pests can get into it.  I put a large rock on top to keep it in place.   When you check the trap, pull the newspaper out over a bucket with a couple inches of soapy water in the bottom (dish soap works fine).  I was surprised that these didn’t work for me; I only found one slug underneath, but no earwigs in the three traps that I set.

Rolled up newspaper (2nd place)

How to:  dampen a sheet of newspaper, roll it up, set it out on the ground.  I weighted it with a rock since it gets breezy here.  When you check the trap: shake the newspaper over your bucket of soapy water.  For me this worked best in the morning, before the paper dried up and the earwigs fled elsewhere. 

Far and away what has been working the best is…

Baited pitfall trap (Winner)

How to:  Use old containers that will hold liquid (butter tubs, yogurt cups, etc.)  The bait is a combination of water, some soy sauce, and a dab of molasses, with a thin layer of vegetable oil carefully floated over the top.  I mixed up a batch of bait, sunk the containers out in the garden with the lip at ground level, then went back out and poured an inch or so of the liquid into the bottom.  I used a small container to add a little bit of vegetable oil over the top, so that it formed a more-or-less continuous thin layer.  There have been loads of earwigs in every trap each day, although I haven’t had to empty them yet (today is the third day).  The only “con” is that a few spiders and other non-earwig-insects have also been trapped.

Drew, Jim and I spent Saturday at the farm practicing division of labor.  My morning was spent taping up some of the tube connection points in our Freshman test field irrigation system.  Occasionally one of the inner-hose-inside-outer-hose connections, currently held together by friction alone, will pop and we’ll arrive at the field to see the evidence of an uneven timed irrigation etched as water lines in the clayey soil.  We decided to try duct tape and see how it holds.  No doubt it will be fine for now, but when the high heat comes in July and we see 100?-plus days, the adhesive might get gooey.  We’ll see.

After fixing the irrigation connections in the field, I went on to my next task, which was hoeing the last two beds and planting squash and zucchinis (with radish seeds mixed in with each squash and zucchini hole) , turnips, and cucumbers.  I’ve read that if you plant the radish in with the squash and zucchini, and let the radish grow along with the squash and eventually go to seed, this will help in repelling pests that plague cucumbers and squash.  I did not put radish seeds into the cucumber hills because there is already a row of radishes planted right next to the cucumbers.  (As previously mentioned, the radishes that will go to seed, and the turnips that we have planted partly for seed, can be mixed with clover in our next cover crop to boost nitrogen content.)

While working on the irrigation taping and planting, I was excited to see that some evidence of Drew’s planting on March 18 (10 days prior) was peeking out of the ground – we have radishes and lettuce up.  In addition, the potatoes have broken through (planted on March 7, so at 21 days).  It’s great to see them there since we have been worried about the high clay content of our soil, which made it very difficult to work with while planting.  We don’t have nice crumbly stuff to cover the seeds over with, but instead gobs of stuff that’s either sticky if it’s wet, or sharp and chunky if it’s dry, and no other state in between.

Later, we installed our “Deer Fence,” definitely a lot of steps down from what Willow described in her recent post … this is another idea that I read about on the internet and cost us $20 and half an hour’s time, so perhaps it will be worth just as much as we put into it.  It’s not going to give us the peace of mind that a properly installed, post constructed 8’ fence would, but on the other hand we haven’t yet had a chance to really evaluate how much deer danger our little test field is in.  Evidence so far is circumstantial and anectodal:  The circumstantial evidence is the scores of deer paths trodden down in the meadow grasses on the middle portion of the farm where the test field is located, and the occasional dancing hoofprints we would see in the test field while it still had a cover crop planted; and the anecdotal evidence comes from our neighbor Dave, who lives full-time on his place.  Dave tells Drew that “there’s a whole clan of deer that meet up on your meadow every evening – they’re so beautiful, just a wonderful sight to see – and so many of them!”  This is hardly heartening, but still, we are committed to trying the low-tech, small solutions first for each of the needs we encounter on the farm, and then evaluate how well those worked before moving on to a more intensive solution.

The low-tech deer fence is made with 6 t-posts and some 80-pound test line, stretched  at deer shoulder-height and rump-height.  The concept is that Mr. Deer comes across the meadow toward our field, bumps some body part into this stretched length of fishing line, and is spooked by the concept that there’s an invisible obstacle that has reached out and touched him.  If he ponders jumping over it, he will think twice because a deer does not want to jump over something he can’t see and fully evaluate.  Fine – we’ll see about that.  Will the deer think the way that guy on the internet said they would?  (His t-post and fishing line fence has kept the deer out of his garden for two straight years, so maybe??)

But here’s the really cool thing about the deer fence:  It sings.  The line is stretched tight, and when you get your ear a few inches from it you can hear strange ghostly wailing harmonics.  It’s a beautiful sound.  I wonder if the deer will like it.

They like tomatoes also.  Not just the brassicas.  Well, the time to get them is at night, when they’re out feeding, but if a midnight run to the farm field doesn’t sound appealing (and it really doesn’t anymore), then I just dig around the base of the victimized veggie plant, find the little critter, and send him to greener pastures in some other place and time. A month or two ago, losing a plant was devastating.  Now, it’s just a part of it all.  I know everything is… Read the rest of this article »

Three farms are starting from scratch.

They are turning the dirt and hoping to be successful enough to turn a profit, and to become a valuable part of their communities as suppliers of organically grown food.

Peaceful Valley is giving them a head start by offering them special pricing as part of this Freshman Farmer program.
