Includes:

1 No-Wasp Net Bag (60 cm X 60 cm , 24″ x 24″ ) Material: Nylon Mesh

Nesting trays not included

No-Wasp Net Bags are generously sized with an extra-wide, draw-string opening. The bags have room for stacked nesting trays and Mason Bee Houses with the cocoons inside. Place trays and houses into net bag, draw it closed, and the cocoons are safe from pests. Staying pest-free means viable cocoons come spring.

No-Wasp Bags are an important part of keeping a healthy Mason Bee population from year to year. Bags are washable and fold flat for storage.

Design Principles

Protection from pests is two-fold.

(1) Parasitic wasps and other pests will be attracted to the nest but will not be able to enter the bag and nest to parasitize developing bee larvae.

(2) Parasitic wasps that are previously in the nest will develop and come out to find additional bee cocoons, but first wasps have to leave their nesting chamber and mate. While they are trapped inside the netting, mist-spray them with a mild soapy solution. This will kill these wasps that are flying around inside the net bag.
