What are flea "bombs"? Flea bombs or foggers are pressurized cans of insecticide that totally release their contents once the trigger is pressed. In use, flea bombs are placed upright in the center of a room. When the trigger is pressed the entire contents of the can are sprayed upward as a fine aerosol spray or mist .   Flea foggers usually contain an insecticide to control adult, biting fleas plus an insect growth regulator such as methoprene , or the trade name Precor , that prevents larval fleas from developing into adults - thus " breaking the flea life cycle ". Do flea foggers really work?   Unfortunately foggers, and other total release insecticides, are not a good way to apply insecticides. This is because the foggers produce spray droplets that are too large to stay suspended in air long enough to disperse to "every nook and cranny" of the room as advertised. Essentially any surface that is shielded by furniture, is not treated . Plus, surfa

Reports of "mysterious bug bites" increase in winter Every winter the number of people contacting us through our 'Bugs website about mysterious bug bites seems to increase.

Fleas can be extremely annoying and even dangerous to you and your pet. Fleas are ecotoparasites that feed on blood and can transmit diseases and some internal parasites like worms when they bite. In fact, did you know that one of the deadliest human pandemic plagues in all history was spread by flea bites? This was the Black Death plague of the middle ages (1349-1352; click the link if you are curious). In modern times, however, fleas are more of a nuisance than a real health threat although flea bites can be so stressful and prone to infection from scratching for some animals that death has occurred. Fortunately, pet owners today have a wide variety of ways to combat an existing flea infestation and to pro-actively prevent fleas from gaining a foothold in the first place. Fleas can be controlled by treating pets directly with a variety of flea medications and carpets, furniture and pet bedding can be treated with very low toxicity chemicals that stop flea development.

We have a series of articles at our 'Bugs site to encourage homeowners to do their own pest control rather than relying on professional exterminator services. We believe that in many, perhaps most, situations homeowners can manage pests more economically and with less environmental impact. Articles are arranged by pest category (pests that bite and sting or transmit disease, nuisance pests, structural pests, and so forth) with information about regional importance.

varied carpet beetle I was a volunteer in the "Entomology (Study of Bugs)" section at a site called AllExperts**. The site allowed users to ask questions of volunteer "experts" in a variety of categories. As a volunteer I got a variety of interesting and sometimes funny questions but one category stands out because of how often it is asked, often using very similar words. The question starts out something like "I have [ small or tiny or little ] black bugs on the walls in my ____________. They crunch when I squish them. What are they?" Sometimes the question includes a picture but often it does not. While there are many insects that fit this general description the one that you are most likely to find in the typical home are dermestid beetles , commonly called carpet beetles (see photo above). Carpet beetle adults can be all black to mottled grey, white, and brown, and round to oval in shape. They are all fairly small.   carpet beetle larva Car

Bugs the invade homes and which need control? Most people believe there is a long list of insects that invade homes and can potentially damage our valuables or even hurt us. The truth is the list is very short and in modern society these species pose little real threat to us or our homes. Oftentimes the drastic steps we take to avoid these bugs are potentially more damaging than the insects themselves. In other words " the cure is worse than the disease ". I've been answering questions about insects from the general public for many years (see my bio here ) and the following eight are the ones most often found in homes. These eight represent the vast majority of insects that ever enter homes and none pose a significant threat if reasonable levels of sanitation are maintained. The Big Eight Household Bugs ants carpet beetles cockroaches fleas (only if pet dogs or cats are housed indoors) house centipedes meal moths silverfish spiders Obviously individua

Why are bed bugs returning to big cities like NYC?   Human b ed bug s , Cimex lectularius , are almost unique among ectoparasitic insects in that they specialize in feeding on human blood, and only on human blood ( click here if you're not sure what bed bugs look like). While there are plenty of insects and other arthropods that feed on the blood of animals such as birds, reptiles (snakes and lizards), and mammals (hairy creatures that give birth to live young and have mammary glands) most will happily feed on a variety of different animals as well. For example, certain mosquitoes may select a bird for one meal then a human for the next meal, and so on. This is how West Nile virus , for example,  moves between birds and humans. The human bed bug, on the other hand, feeds only on us . Human bed bugs , along with body lice , have always been closely associated with their favorite meal ticket, namely people. Both insects are even the subject of familiar children's nursery rhym
