Trap Spacing and Placement: When trapping for woodborers or bark beetles, separate traps with different lure combinations by at least 30 meters (98 feet).
Method Notes:
In 2011, it is strongly encouraged to change to the wet collection cup method in multi-funnel traps, where possible. The wet method will increase the effectiveness of the traps and will provide better quality specimens to the identifiers, increasing the likelihood of detecting and identifying exotic pests early.
Approved Lure(s):
| NAPIS Code | Product Name | Dispenser | Effectiveness | Compound(s) |
|---|---|---|---|---|
| 103 | Alpha Pinene UHR Lure | polysleeve | 56 days |
alpha pinene |
| Ethanol Lure | polysleeve | 56 days |
ethanol |
Lure Placement:
Do not include lures for other target species in the trap when trapping for this target.
Lure Notes:
The release rate of this lure is highly temperature-dependent. However, CAPS has listed a conservative length of effectiveness that will be effective for even the warmest climates in the CAPS community.
