Fast delivery from order ( 3 days) . I was Very impressed with quality of construction and components out of the box. Instructions were easy to follow and additional info provided on pest species was helpful. I have been using for 6 weeks ( Jan/Feb) when we have high mosquito and midge activity from nearby bush land. We generally don’t go down the garden without protective sprays. Emptying the sieve shows high kill numbers for pests, but quite a lot of collateral impact on moths - not all of which are problem species. Mosquito numbers have dropped, but still enough to cause problems so far ( we’ve had plenty of rain over last 6 weeks too). Due to size of garden area and mutiple potential sources of pests, I will need to relocate the unit a couple of times to see if we get more impact. 4* so far due to this aspect, but I’ve no doubt it is effective at killing mosquitos.
