Remove insect eggs in your garden with a lint roller
For the gardener who wants to limit damage to crops and vegetables you should consider how to remove insect eggs. Preventing the eggs from ever hatching because they’ve been removed from the garden entirely is far more effective than spraying.
This past spring I had someone share with me a tip that makes the task of removing insect eggs in your garden much easier. He uses an inexpensive lint roller to remove insect eggs. You can buy a travel sized lint roller like the one in the picture below at Walmart for 99 cents.
An alternative to lint rollers
If you don’t want to go buy a lint roller to remove those pesky eggs you might have a roll of sticky tape like duct tape around the home. Pull of 8 to 10 inches of it and stick itself together in a loop with the adhesive side out. With one hand hold the tape and apply your other hand on the opposite of the leaf to give you something to press against. Touch the tape to the eggs and apply light pressure until all the eggs are removed.
When eggs are laid next to large leaf veins
With crops like zucchini where there is a large vein on the backside of the leaf the duct tape actually works better than the lint roller. When the eggs are laid next to those large veins the round lint roller will roll onto the vein and pass right over several eggs. In these instances the duct tape works better. When pruning and removing insect eggs from our squash plants I now use only the duct tape.
Watch insect eggs get removed with a lint roller
After trying it I had to get a little video to show just how well it works. Typically we use the lint roller on cabbage, broccoli, kale and cauliflower.
This cool little tree frog is hunting for insects in the Swiss chard out in the garden. Each evening I can hear their cool little songs. No idea how many insects one of these can eat during the course of a week, but I’m glad to have him around.
Any gardener who has grown tomatoes know how destructive the horn worm can be in your tomatoes. If not caught in time these little green eating monsters can destroy your tomato crop. Fortunately if you find them early they are easy to control.
We weren’t in the garden for about 4 days and I missed the signs of horn worms until they had done some serious damage. We went through our plants and plucked off any horn worm caterpillars we spotted.
When you spot hornworms
As soon as you see them, or their droppings, examine your plants and remove any of the caterpillars you can find. Dispose of them accordingly. They blend in amazingly well and several are going to be missed. Any missed will be controlled with the BT
Bacillus Thuricide to control hornworms
The name may sound intimidating, but BT is actually a bacteria and is absolutely organic. Gardening stores will often carry it or you can get it from Amazon.
We like to mix up a gallon of it at a time in an inexpensive little sprayer like in this picture below. It cost us about $12 and is on its third season.
As a slight aside, I would recommend writing the contents of the sprayer on its side with a good permanent marker. We also have a dedicated set of cheap kitchen measuring devices dedicated to just our garden.
After the BT is mixed according to the instructions bottle simply apply a heavy mist to all the leaves on your tomatoes. The caterpillar will eat the leaf, ingest the BT, and will die within 24 hours. Generally I find them hanging dead the next morning.
In this picture below you see one of the large hornworms I missed when picking them by hand. Often times you will also see them hanging after they have turned a dark brown color. You can leave them or toss them into the yard.
You can be proactive
Instead of waiting until you see these destructive caterpillars to apply BT you can head them off at the pass. Weekly I try and apply BT to all our plants. While utilizing this defensive measure in our tomatoes the hornworms just don’t survive long enough after hatching to do much damage.
Video on using BT
Towards the end of this video you can see what their frass looks like. You will find it at the base of the plants and is an indication that you’ve got tomatoes being destroyed by this insect.
