You should be OK with a relatively small number of traps if you hang them in shady areas near fruit.

However, if you are growing late summer/fall fruiting raspberries, traps may not be as useful because flies are likely already there. For us, traps only provide actionable information in really early fruiting crops, such as strawberries.

I encourage you to get in touch with local entomology resources to get information specific to BC. Tracy Hueppelsheuser is an entomologist with the Ministry of Ag who may be able to help.

How far apart should bait traps be hung in raspberries? I just have a couple of 20' rows of rasps but want to be alerted when these nasty things arrive so I can be on the alert for them. I first had them last year. Anne noreply@blogger.com
