Wasps Pest Control
Like all social insects, wasps communicate using chemicals released from glands in their bodies, known as pheromones. These pheromones are airborne signals that convey information to other wasps in the area. If you kill one wasp, several more will often appear in an aggressive mood shortly thereafter – this is because of the warning pheromones released by the first wasp. The queen wasp is long-lived but the sterile workers may live only a few weeks, requiring a large output of eggs and raising of new wasps. Early workers are often small because the queen must feed them, but later broods become larger because more food is being brought into the nest by an increased workforce.
Bees Pest Control
Bees are extremely important pollinators and most of the beautiful flowers found in gardens evolved specifically to attract these busy insects. Honey bees are the only insects in the world that regularly supply humans with a type of food. Bees are much less aggressive than hornets or wasps both because they are not insectivores and because they are killed by the act of stinging, unlike the wasps, who boast smooth stings. The dances which bees conduct to communicate that they have found a source of nectar and pollen has fascinated mankind for decades and has allowed these insects to inform other bees of the distance to suitable flowers for millennia.
Cockroaches Pest Control
Although they are physically unappealing, spiders are fascinating creatures in their own way and have many unique adaptations that set them apart from nearly all other animals on Earth. Their silk webbing, formed from a liquid exuded from glands on the abdomen which hardens into strands on contact with the air, is stronger than steel of the same thickness would be, as well as being many times more elastic. Female spiders often devour the male after mating – or before – which explains why male spiders have elaborate rituals to appease the female when approaching her, and often do so with evident trepidation. Certain species of spiders feed on other spiders, plucking at their webs to make them think that a juicy insect has been caught, when in fact it is an invader intent on devouring them. Few spiders present a bite poisonous enough to endanger a human, but a few, such as the Sydney funnel web spider, can occasionally give a fatal bite.
Butterflies Pest Control
Well known as the light-hearted, brightly coloured visitors whom we see fluttering around spring and summer flowers, butterflies drink nectar and lay their eggs on a wide range of different plants, many of which are wild and some of which are of economic importance to man. The juvenile butterfly, or caterpillar, is completely flightless and feeds for a time on the host plant, before building a papery chrysalis inside which it metamorphoses into the completely different adult. The bizarre process involved in this transformation includes secretion of digestive acids which melt most of the caterpillar’s tissues – the adult butterfly grows out of a few cells left from this drastic reorganisation. Even more strangely, some butterflies and moths may be able to remember things they learned as caterpillars even though their bodies are almost completely broken down and regrown during metamorphosis.
Beetles Pest Control
Ants are one of the most ubiquitous insects, and a South American legend relates that the whole Earth was formed out of them, because wherever you dig, you are sure to find red ants. Although this is not quite true, these wingless wasps are highly effective at colonising and surviving in every kind of habitat. They are often highly aggressive creatures, with specialised soldier castes for fighting, attacking, and defending. Some species raid other ant nests for larvae and pupae, with the stolen ants then serving as slaves in the victors’ nest. The queen is the centre of any ant nest, laying thousands of eggs and keeping the numbers of the ants renewed.
