From bedbugs and carpet mites to mosquitoes and toxic moths, the insect population in our homes is increasing. We're not overrun just yet, but many of our most common pests have had a good year and a few exotic ones have arrived too.

Experts say pests are now blinking at the edge of the public health radar screen. We only have to look at our European neighbours to see how the problem is escalating. In Belgium, the army had to be called in to tackled an infestation of ticks recently.

For instance there has been a 500% increase in the bedbug population in the UK in just 12 months. The problem is that two-thirds of people don't initially know what the bites are and don't know to take action against the pest, says David Cain of the Bedbugs website (see Internet links on right).

The key signs are bloodspots from the bites on sheets, and skin irritation. Adult bedbugs are the size of an apple pip and their bites tend to itch intensely. Mr Cain says he's often called out to people who claim to have up to 150 bites.

"We had a case recently where there was an estimated 50,000 bedbugs in a single bedroom flat," he says.

And getting infected with bedbugs can be as simple as sitting on a seat after someone who has a severe case of bedbugs.

Pest expert Dr Moray Anderson says we are making life easier for pests. We travel more and so pick up bugs, clean our homes less and the climate is changing - our winters are less severe and our summers wetter, perfect conditions for pests to thrive.

Knowledge is 'best protection'And there's the reduction of weapons in the pest controller's arsenal. Chemical safety laws are tightening, fewer insecticides are legal and the bugs are becoming immune to the handful that are left.

"We are making sure that we are not using quite so toxic chemicals, quite rightly so," he says. "But we have to be very careful we don't get the balance too out of kilter."

One pest that's thrived this summer is the mosquito. The rain provided little puddles everywhere where they can breed, free from predators. There are no fish lurking in that bucket left out in the garden and it can prove a perfect nursery for hundreds of mosquitoes.

But what really worries public health officials is not the number of mosquitoes, but the variety. They've set up "Mosquito Watch" to keep an eye out for Asian Tiger mosquitoes which can carry West Nile virus and Dengue fever.

Environmental health officers now patrol airports as the insects may hitch rides in plane cabins and breed in stagnant water close by.

Warmer winters could also be to blame for the arrival of some exotic pests. The Oak Processionary Moth is on its way from southern Europe as warmer weather fosters its survival. It was recently spotted in London for the first time.

Lyme disease can attack the heartThe caterpillars strip oak trees of their leaves but are also toxic to people. Their minute hairs cause severe skin irritation, allergic reaction and, if breathed in, can be life threatening.

The tick is nothing new to this country but can harbour a nasty bacteria. It's an arachnid, whose eight legs grip the skin as its head burrows beneath to drink many times its own weight in blood. It can carry Lyme disease, a bacterial infection which can attack the skin, heart and nervous system. The early symptoms can be similar to severe flu and often it's wrongly diagnosed.

Official figures on tick numbers aren't available yet, but the authorities are sufficiently worried to be doing a count. Another factor is the increase in urban wildlife, especially deer, who are thought to transport the pests into gardens and from there, into our homes.
