Bedbugs have been bothering humans since caveman times, study finds

Independent30-05-2025

A new study suggests bedbugs may have been bothering humans for about 60,000 years, with their populations booming as people formed the first cities.
The research, published in Biology Letters, examined bedbug genetics and found two lineages: one that stayed on bats and one that targeted humans.
As humans built early cities like Mesopotamia around 12,000 years ago, bedbug populations thrived, making them one of the first human pests.
Professor Warren Booth notes that humans likely carried bedbugs from caves when they moved out around 60,000 years ago, resulting in less genetic diversity in the human-associated lineage.
Bedbug infestations saw a dramatic 35 per cent increase between 2022 and 2024, highlighting their resurgence after near-eradication due to the chemical DDT.

Gardeners told to use 22p kitchen staples for ‘vampire trick' which can banish slugs from your garden for good

A GARDENING expert has revealed a 22p hack to banish slugs from gardens using a very common kitchen staple. Now that summer is finally here, many Brits will be looking for ways to spruce up their outdoor spaces - including getting rid of any nasty critters. 1 Slugs and snails are notorious for wreaking havoc on gardens, in particular during rainy patches when they come out in their swathes to feast on crops and plants. Over the years, experts have come out with a whole host of - often ineffective - methods to combat these garden pests. From splashing beer and sprinkling eggshells on crops to surrounding veg patches with copper tape. But one savvy expert believes they have found a cheap, store cupboard hack that could rid gardens of these pests once and for all. Gardeners have been urged to introduce garlic to their gardens as a means of deterring the slugs. And at just 22p a bulb, this could be the cheapest hack yet. Garlic wash involves boiling two whole bulbs of garlic in two litres of water until they soften, then pulping them to make a juice. After removing the garlic skins, the concentrated liquid should be diluted with water and put into a spray can which can be used over plants. The liquid should then be sprayed on plants across the summer right into October. A gardening expert wrote: "We use garlic wash as a slug deterrent on the nursery. 6 ways to get rid of slugs and snails "Please find below the recipe that we use and find very effective. The quantities aren't exact and you can always alter them as you wish." If the smell of garlic is too pungent Homes & Garden writer, Thomas Rutter, suggests using cucumber instead. Stopping slugs and snails using the cucumber hack is surprisingly simple. While it may not eradicate these pests, it can help gardeners control their numbers. Rutter said: "First, raid your fridge drawer and retrieve a cucumber, before slicing it thinly. "Don't worry about the quality of the cucumber here, in fact, it is best to use those that are past their best." Rutter then advises to place the slices near your more vulnerable plants in the evening. Slugs and snails will be lured to the scent and moisture of the cucumber. Then, after a few hours or the following morning, you can collect the pests and dispose of them. It's not too dissimilar from companion planting or trap plants for pest control. But what's better is that it's a chemical-free approach, safe for pets and requires almost no effort.

New research strengthens case for age of ancient New Mexico footprints

June 19 (Reuters) - A new line of evidence is providing further corroboration of the antiquity of fossilized footprints discovered at White Sands National Park in New Mexico that rewrite the history of humans in the Americas. Researchers used a technique called radiocarbon dating to determine that organic matter in the remains of wetland muds and shallow lake sediments near the fossilized foot impressions is between 20,700 and 22,400 years old. That closely correlates to previous findings, based on the age of pollen and seeds at the site, that the tracks are between 21,000 and 23,000 years old. The footprints, whose discovery was announced in 2021, indicate that humans trod the landscape of North America thousands of years earlier than previously thought, during the most inhospitable conditions of the last Ice Age, a time called the last glacial maximum. The age of the footprints has been a contentious issue. Asked how the new findings align with the previous ones, University of Arizona archaeologist and geologist Vance Holliday, the study leader, replied: "Spectacularly well." Homo sapiens arose in Africa roughly 300,000 years ago and later spread worldwide. Scientists believe our species entered North America from Asia by trekking across a land bridge that once connected Siberia to Alaska. Previous archaeological evidence had suggested that human occupation of North America started roughly 16,000 years ago. The hunter-gatherers who left the tracks were traversing the floodplain of a river that flowed into an ancient body of water called Lake Otero. The mud through which they walked included bits of semi-aquatic plants that had grown in these wetlands. Radiocarbon dating is used to determine the age of organic material based on the decay of an isotope called carbon-14, a variant of the element carbon. Living organisms absorb carbon-14 into their tissue. After an organism dies, this isotope changes into other atoms over time, providing a metric for determining age. "Three separate carbon sources - pollen, seeds and organic muds and sediments - have now been dated by different radiocarbon labs over the course of the trackway research, and they all indicate a last glacial maximum age for the footprints," said Jason Windingstad, a University of Arizona doctoral candidate in environmental science and co-author of the study published this week in the journal Science Advances, opens new tab. The original 2021 study dated the footprints using radiocarbon dating on seeds of an aquatic plant called spiral ditchgrass found alongside the tracks. A study published in 2023 used radiocarbon dating on conifer pollen grains from the same sediment layers as the ditchgrass seeds. But some scientists had viewed the seeds and pollen as unreliable markers for dating the tracks. The new study provides further corroboration of the dating while also giving a better understanding of the local landscape at the time. "When the original paper appeared, at the time we didn't know enough about the ancient landscape because it was either buried under the White Sands dune field or was destroyed when ancient Lake Otero, which had a lot of gypsum, dried out after the last Ice Age and was eroded by the wind to create the dunes," Holliday said. Today, the landscape situated just west of the city of Alamogordo consists of rolling beige-colored dunes of the mineral gypsum. "The area of and around the tracks included water that came off the mountains to the east, the edge of the old lake and wetlands along the margins of the lake. Our dating shows that this environment persisted before, during and after the time that people left their tracks," Holliday said. The area could have provided important resources for hunter-gatherers. "We know from the abundant tracks in the area that at least mammoths, giant ground sloths, camels and dire wolves were around, and likely other large animals. Given the setting, there must have been a large variety of other animals and also plants," Holliday added. The climate was markedly different than today, with cooler summers and the area receiving significantly more precipitation. "It is important to note that this is a trackway site, not a habitation site," Windingstad said. "It provides us a narrow view of people traveling across the landscape. Where they were going and where they came from is obviously an open question and one that requires the discovery and excavation of sites that are of similar age in the region. So far, these have not been found."

I'm a gardening pro – my easy steps – including a £2.25 Dunelm trick – will banish garden pests like aphids this summer

WE may well be seeing lower slug and snail numbers this summer thanks to colder weather in winter and the recent dry spells. But mother nature never makes it easy for us. Instead - of course - there's a new pest in town. 2 Aphid levels have rocketed this year - and the RHS reckons it's top of the list of gardening queries to their hotline. There's over 500 different species found in the UK - and can be red, yellow, black, green, brown or pink. They feed by sucking sap from plants - and can cause severe damage - including distorted growth, sooty mould and plant viruses - and sometimes plant death. Chelsea award winning gardener Adam Woolcott - and Webb ambassador - gave Sun Gardening some top tips on how to tackle the most common early summer pests. APHIDS Physically remove the aphids from the stems and leaves. Use natural insecticidal soaps. Blast off with water jets. Encourage predators such as ladybirds, lacewings, and hoverflies VINE WEEVIL Both the adult vine weevil beetles and their larvae cause damage. Adults — all female — chew distinctive 'U-shaped' notches in leaves, particularly on evergreen shrubs like rhododendrons, escallonias, and viburnums. Underground: larvae feed on plant roots and can kill container plants like Heucheras. Remove adults at night when they're most active Break the life cycle with biological controls such as nematodes (apply in spring and autumn when grubs are active) Chemical treatments are a last resort, but offer longer-term control LILY BEETLE The bright red beetles and their larvae are both covered in their excrement. They can strip a plant in days, affecting flowering and bulb health. Remove beetles by hand where practical Encourage wildlife into the garden. Birds and ground beetles will eat the larvae Grow a resistant variety. Tolerate some damage if you can — total eradication isn't always necessary. CATERPILLARS Especially troublesome in veg patches. Cabbage white butterfly caterpillars love brassicas, while box tree caterpillars are spreading rapidly across the UK, stripping foliage as they go. Remove the caterpillars by hand if you can and destroy any badly affected plants (if practical) to stop the infestation from spreading. Use biological sprays like nematodes. In some cases, hot water and a mild detergent can help. Ecover is on sale at Dunelm for £2.45. As a last resort, chemical controls can be effective Also in Veronica's Column this week... Top tips, Gardening news, and a competition to win a £250 lawnmower NEWS KING Charles made a surprise visit to Windsor Flower Show last Saturday. Celebrities including Alex Jones and Kirsty Gallacher were at the one-day show - which had wonderful village fair vibes, vegetable and cake competitions and fantastic floral displays. TOP TIP JUNE is actually a good time to take Hydrangea cuttings - and get your own plants for free. They'll have produced some soft green growth - which is what you want. Choose healthy, non flowering shoots that are 10-15cm long and cut just below the node (the leaf joint). Don't collect cuttings from plants with leaves that are turning brown. And try to collect in the morning if you can. Remove the lower leaves - leaving just one or two at the top. Then dip the end in rooting powder or gel - then pop it straight in a pot. You could splash out on seeding and cutting compost - but multi purpose will do - just add a bit of grit or perlite. Then keep them out of direct sunlight and keep moist. They should have rooted within about a month. NEWS A RARE 'sheep-eating' South American plant has flowered in an English primary school for the first time. The Puya Chilensis, with its iconic spike pattern, is normally found in the Andes in Chile. But after it was planted 10 years ago by school horticulturalist Louise Moreton, it has sent out a 10ft spike at Wicor Primary School in Portchester, Hants. It's called a Sheep Catcher as it would normally entangle wildlife, hold onto it - and then when the animal died - would take the nutrients. Ms Moreton said it was exciting but a worrying sign of global warming. WIN! Keep your lawn looking its best this summer by winning a Webb Classic Self Propelled Petrol Lawn Mower worth £249.99. To enter visit or write to Sun Webb competition, PO Box 3190, Colchester, Essex, CO2 8GP. Include your name, age, email or phone. UK residents 18+ only. Entries close 11.59pm. July 5, 2025. T&Cs apply. TOP TIP IF you want to get more flowers from your sedums (now called Hylotelephiums) and prevent them from collapsing - pinch them out around now. Pinch off around four sets of leaves down - which will make them bushier. JOB OF THE WEEK Weeds thrive this month - keep on top of them by hoeing. Tie in sweet peas, and give your plants a good feed - liquid seaweed feed is great - and Tomorite works with nearly everything. Give agapanthus a high-potash feed every couple of weeks.
