Residents partly of Australia are being flooded with an intrusive, serial parasite in their yards– one that can “spreading very quickly and easily” and wrecking some trees and plants.
But Aussies are obtaining imaginative with handling their citrus gall wasp problem which targets citrus trees, mainly lemon and grapefruit, and are making use of home appliances consisting of home microwaves and bar-b-ques to do away with them permanently.
One Perth male called Charlie was surprised to find “bulges on the stems” of his lemon tree, informing Yahoo News Australia he had actually not seen them in the past. The citrus gall wasp is an Australian indigenous bug initially from north NSW and Queensland yet is currently developed in the majority of Perth residential areas after spreading out throughout the nation.
The eggs are stocked brand-new shoots of citrus trees and the tree responds by generating unique galls around the creating larvae. Adult wasps after that arise from galls.
“Advice from people was to cut the infected stems, bag it and place it out in the sun to kill the gall wasp inside,” he informed Yahoo after requiring to Facebook with his issue. “Another recommendation was to burn or microwave it.
” I selected the last,” he added. Previously another homeowner cooked the stems on the barbie.

How to manage a citrus gall wasp infestation
A photo shared by Charlie shows a bowl full of off-cuts from his lemon tree with noticeable bulbs protruding from the stem which he ” destroyed in the microwave”. And while burning or cooking them might seem odd, there is some logic behind it.
Pruning is said to be a suitable control method, and one homeowners can undertake easily. However, wasps can still emerge from offcuts if pruned too close to their usual emergence period â usually between September and December. So burning can be one way to mitigate any risk associated with wasp-infected off-cuts. Shredding and mulching or placing the branches in a sealed bag can help too.
” I did 5 minutes [in the microwave],” Charlie said. ” I believe it’s even more reliable than getting and sunning it. Especially when gloomy or drizzling. I think it eliminates the eggs or pupae in the stem.”

If left untreated, the galls created to house the larvae are known to disrupt water and nutrient flow which can weaken trees and affect productivity. Heavy infestations will often reduce fruit size and quantity over time.
Thankfully Charlie said his lemon tree was unscathed in the end and has grown ” great deals of fruit”. “But we simply require to continue top of the problem,” he included.
