Insecticide Resistance Mosquitoes like fruit or drain flies are easily knocked down or killed with exposure the any broad spectrum insecticide. However they possess a high level of resistance to common residual insecticides. Meaning if a Mosquito is exposed to a direct wet application of any insecticide, it will die. Residual insecticides leave a layer of active ingredient on the treated surface which is picked up by an insect and soon after the insect will be killed. With any Mosquito infestation, there will be a dominant amount of the group which will not be affected by this residual.
For this reason, when Ecosan Solutions applies an indoor residual treatment for Mosquitoes we use products with a mode of action which differs from that which Mosquitoes are resistant. This increases the efficacy of our treatments. The chemistry in these solutions is also less toxic than common products like pyrethroids.
Mosquitoes indoors Some buildings design and architecture will increase the likelihood of having issues with Mosquito’s. Buildings with doors opening and closing during dusk or early evening may find this pest venturing inside. They may nest and multiply. EcoSan have seen buildings in the CBD area with thousands of persistent Mosquito’s inside. Homes and structures with moist foliage in garden areas will have increased amount of Mozzies also. Our indoor treatments are very low odour, Low toxic and safe to re enter after a short amount of time.
Mosquitoes outdoors. Spraying for this pest outside using often Misters or Thermal foggers will knock down Mozzie populations for around two weeks. Long residual control of this pest, depending on the environment can be difficult. Some other methods include;
Insect growth regulator This treatment can be routinely applied to sewerage septic tanks. Mozzies will lay eggs in septic tanks due to the standing water. The IGR will prevent Mosquito larvae from maturing into an insect.
Aqua Film If you live near standing water like a still pond or holding facility, a silicon type film can be added to the water. This coats the surface layer and the larvae of the Mosquito cannot breath as they float on the surface. This should only be applied on private land as council consent is required for crown property.
Circulate standing water Fish ponds, or other standing water which Mosquitoes love to lay eggs in can be sorted without the use of chemicals by adding a pump to keep water circulating or moving. This helps to control algae growth also.
Treating mosquito in most environments around the home is not impossible with even the most persistent situations being alleviated. Mosquitoes have more life stages than most insects and understanding the activity and habits of this insect will allow the pest management technician to carry out control treatments with excellent results.
