What Bugs Come out in Spring?

With the weather becoming warmer some of the UK’s insects are now becoming more active. So what bugs come out in spring? These include ants, bees, queen wasps, and caterpillars.


What bugs come out in spring?The worker ants will frequently enter dwellings searching for food, in particular sweet substances. While they are not a risk to human health, they can be present in sufficient numbers to cause a nuisance in houses and in gardens. The ants will be coming from several nests so locating one nest and destroying that will have a limited effect on the pests.

We will treat the infested and surrounding areas with one, or a couple of insecticide sprays. gel baits may instead, or alongside could be used. These insecticides are the most modern insecticide available.


You will see bees entering a hole in the ground or into a wall or roof. Where they nest can depend on the species. It may not be necessary to destroy the nest. We will always firstly attempt to remove the nest. If this is not possible or safe to do so then treatment may be the only option.  The technician will be able to tell you what sort of bees they are. This is usually either bumble bees, honey bees or a wild species such as masonry or mining bees, there are many sub species of wild bees within these groups.What bugs come out in spring?

If necessary then treatment with an insecticide may occur. All insecticides are biodegradable, almost odourless, non tainting & do not corrode or stain. They are not highly toxic towards mammals but are extremely so to all forms of crawling and flying public health pests.

Queen Wasps

In Spring the new queens will emerge from their overwintering and will begin starting a new colony. A nest will get larger until the Autumn and it is in the Autumn and the early Winter when they are at their most aggressive. This is when they are likely to sting people. Wasp nests can stain ceilings and even eat through them in some instances.

A residual insecticide will be used to treat the nest or a fogging treatment may take place in your loft.


There are many types of caterpillar here in the UK. some of these such as oak processionary moths, in their larval stage and brown tail moths can cause problems for people. These problems include asthma and skin irritation for some people. They are most commonly found around the south and east coasts of England, but can become abundant in warmer temperatures. The caterpillar form of these moths have urticating hairs, which cause extreme irritation when in contact with human skin.
