Mystery Beetle Infestation: Not Croatian Almond Bark Beetles

A homeowner brought a lavender sachet from Croatia in 2007, later discovering beetles they believed to be Scolytus amygdali (Croatian almond bark beetle). The insects appeared in two rooms in spring 2008, were professionally sprayed, but returned the following spring in smaller numbers. Recently, beetles were found in stuffed animals and pantry items like herbal teas and spices.

Expert Assessment

Based on the biology of Scolytus amygdali, which feeds exclusively under tree bark, this is almost certainly a misidentification. True almond bark beetles do not infest fabrics, stuffed toys, or stored food products. The beetles described are likely a different species entirely—possibly a stored product pest or carpet beetle.

Recommended Action

Proper identification is critical for effective control. The homeowner should:

• Collect several intact specimens
• Submit them to the state university entomology department or county Cooperative Extension office for identification
• Search online for "[your state] agriculture extension service" to find local resources

Once accurately identified, targeted treatment can be applied. Spraying without knowing the exact pest is ineffective and potentially hazardous.
