Déchaumer avec une déchaumeuse   Si une barrière de 1 à 2 cm vous empêche de toucher le sol : vous avec du chaume. Corriger le pH : un sol acide ralentit la décomposition du chaume. Déchaumer si nécessaire. Aération, déchaumage et ramassage des feuilles et semis. Ramasser l'herbe si la pelouse est fertilisée ou traitée, si l'herbe est mouillée et s'il y a du chaume.
"Homes are selling faster and faster in the Montréal area, as the average selling time, for all property categories combined, was 80 days in November, which is seven days less than one year ago," said Nathalie Bégin, President of the GMREB board of directors. "Single-family homes and plexes sold the fastest – in an average of 72 days – while it took an average of 94 days for a condominium to sell," she added. 

Male C. pallida are able detect the pheromones which females release and use them to locate female burrows. When a virgin female is about to emerge from her burrow, she releases a scent that wafts up through the soil and is detected by the antenna of the males. This has led to males developing a very acute olfactory sense. Freshly-killed females have been buried to test whether sound also plays a part in male signaling. In these tests, male bees still dug up the dead females, proving that pheromone signaling is the only pathway. Males have also been observed to dig up other males. This shows that males and virgin females give off similar pheromones. Oddly, males also sometimes dig up other digger bee species. It is currently unknown why this occurs.[6]
