FLIES
Fly and Spider Control Ltd has pest control services for most of New Zealand's winged pests including: houseflies, blowflies, fruit flies, mosquitoes, sandflies and midges. Most flies spread disease through contamination posing a threat to hygiene, and are a common nuisance to humans and animals.
By nature many flies breed and feed in areas of unsanitary conditions, with larvae (maggots) feeding on decaying organic matter (ie. animal manure, grass clippings, garbage etc.) before pupating and finally emerging as adults. Under ideal conditions house flies can complete this entire life cycle in less than 7 days and as they emerge from the pupae in these unhygienic conditions they become contaminated with disease causing organisms. These adult flies may then transfer to uninfested or sensitive food preparation and eating areas contaminating the food with pathogens and causing disease usually in the form of food poisoning.
The treatment and prevention of flies can be achieved with a co-ordinated program that includes:
- Sanitation - is essential to remove and eliminate fly breeding sites. Materials where flies can breed must be removed and the use of mechanical control measures (including screening and air blast doorsand electrocuting grids) can help to prevent adult flies from entering the building.
- Insecticidal controls - should be applied as residual sprays both indoors and outdoors in the form of aerosols, mists, baits or insecticide impregnated strips. Larvicides for the control of maggots may also be necessary to reduce fly breeding in some area.
COCKROACHES
There are several species of Cockroach in New Zealand usually found in warm, dark and moist conditions under cupboards, behind cabinets or in wall voids typically in restaurant kitchens, hospitals and homes.
The adult Cockroach is about ½inch long, pale brown/tan with two parallel black streaks on the pronotum (shield like segment behind the head). They feed on all types of food, and in favourable conditions (warm and moist) can produce very large infestations of hundreds and thousands of individuals.
Because they can easily crawl from rubbish bins or sewers onto clean work surfaces Cockroaches can be a health hazard as they may carry disease organisms on their feet and mouths.
The most effective and long lasting method of controlling New Zealand Cockroaches is sanitation. Where possible food material should be removed and harborage areas sealed off. Residual insecticides applied as sprays, dust, paints, lacquers or baits used in conjunction with aerosol, ULV, mist or fog applications of short term residual insecticides are necessary to control existing populations and to help prevent their recurrence.
