How to Check and Reapply Grease Bands in November: Essential Tips for Pest Control
As winter approaches, it’s important to check and reapply grease bands around your fruit trees to protect them from pests that can cause damage during the colder months. Grease bands are a simple but effective way to prevent pests, particularly winter moths, from climbing up the trunks of your trees and laying eggs. November is an ideal time to inspect and refresh your grease bands to ensure continued protection for your fruit trees through winter. In this guide, we’ll explain how to check and reapply grease bands for pest control.
Why Is Checking and Reapplying Grease Bands in November Important?
Grease bands are designed to stop pests, especially wingless female winter moths, from crawling up the trunk of your fruit trees to lay their eggs. If left unchecked, the larvae that hatch in spring can cause significant damage by feeding on young leaves and fruit buds.
Here’s why it’s crucial to maintain grease bands in November:
- Stops winter moths: Wingless female moths climb trees in late fall and winter to lay eggs. Grease bands trap them, preventing them from reaching the canopy.
- Prevents larvae damage: The eggs laid by moths hatch into caterpillars in spring, which feed on developing leaves and fruit, leading to poor yields and damaged crops.
- Protects young trees: Newly planted or younger fruit trees are especially vulnerable to pest damage, making grease bands an essential preventive measure.
- Maintains pest control: Grease bands can become dirty or ineffective over time, so reapplying fresh bands in November ensures continued protection through winter and into spring.
By regularly checking and reapplying grease bands, you prevent pests from damaging your fruit trees and help ensure a healthy, productive growing season.
Top Tips for Checking and Reapplying Grease Bands in November
1. Inspect Existing Grease Bands
If you applied grease bands earlier in the fall, it’s important to check them in November to see if they are still effective. Over time, grease bands can become clogged with debris, dirt, or trapped insects, which reduces their effectiveness.
- Tip: Examine the bands carefully to make sure they are still sticky. If they are covered with debris or have dried out, they will need to be replaced or refreshed with new adhesive.
2. Remove Old or Ineffective Bands
If your existing grease bands are no longer sticky or have become ineffective due to dirt buildup, carefully remove them from the tree trunk. Removing old grease bands prevents pests from bypassing the barrier and ensures your fresh application will be effective.
- Tip: Gently peel off the old band, taking care not to damage the bark. Dispose of the old band properly, as it may contain trapped insects or eggs.
3. Choose the Right Grease Band
Grease bands are available in various forms, including ready-made adhesive bands and grease compounds that can be applied directly to the trunk. Choose the option that works best for your fruit trees.
- Types of grease bands:
- Pre-coated adhesive bands: These ready-made bands come coated with a sticky substance and can be wrapped around the tree trunk.
- Grease compounds: These are applied directly to the trunk, creating a sticky barrier to trap pests.
- Tip: Pre-coated adhesive bands are easy to apply and remove, making them a convenient option for most gardeners.
4. Apply Fresh Grease Bands Around the Tree Trunk
To reapply grease bands, position the new band around the trunk of your fruit tree at the correct height—usually about 18 inches (45 cm) above the ground. This ensures that pests climbing from the soil are intercepted before they reach the canopy.
- Tip: Wrap the band snugly around the trunk, making sure there are no gaps between the band and the bark where pests could slip through. For uneven or rough bark, use extra grease or adhesive to fill in gaps.
5. Secure the Band Tightly
Once the grease band is in place, secure it tightly to the tree trunk. If you’re using a pre-coated adhesive band, ensure that the sticky side is facing outwards. For grease compounds, spread the substance evenly around the trunk to form a complete barrier.
- Tip: Use string or garden twine to tie the band securely in place, or choose self-adhesive bands for easier application. Be sure to smooth down the edges to prevent pests from crawling underneath.
6. Reapply Grease or Adhesive if Necessary
If you are using grease compounds, it’s essential to monitor the bands throughout the winter and reapply the grease if it dries out or becomes clogged with debris. This ensures that the barrier remains effective for trapping pests.
- Tip: Check the grease bands every few weeks during winter and reapply grease as needed to keep the surface sticky and functional.
7. Monitor for Pests
After reapplying grease bands, monitor them regularly to check for trapped pests. You may see winter moths or other crawling insects caught in the adhesive. This is a good sign that the grease bands are working as intended.
- Tip: If you notice a large number of pests trapped in the band, it may be necessary to refresh the band more frequently to ensure continued protection.
8. Protect All Fruit Trees
Don’t forget to apply grease bands to all of your fruit trees, not just apples and pears. Other fruit trees, such as plums and cherries, can also be affected by winter moths and benefit from the protection that grease bands provide.
- Tip: Make a habit of applying and refreshing grease bands every fall and winter for all vulnerable trees in your orchard or garden.
9. Remove Bands in Spring
Grease bands are typically only needed from late fall through early spring, when pests like winter moths are active. Once the danger has passed, remove the grease bands to allow the tree to grow without restriction.
- Tip: In early spring, carefully remove the grease bands and clean the tree trunk to avoid any potential irritation to the bark as the tree begins its active growing phase.
10. Use Other Pest Control Methods if Needed
While grease bands are effective against pests like winter moths, additional pest control measures may be necessary to protect your fruit trees from other insects. Consider combining grease bands with other methods such as pheromone traps or horticultural oil sprays for comprehensive protection.
- Tip: Regularly inspect your trees for signs of pest damage, and use integrated pest management techniques to keep your trees healthy throughout the year.
